In what direction and at what point does the buoyant force on a body due to liquid act?

The tension in the rope is 196.2 N. The rope is exerting a force of 196.2 N on the object to keep it stationary.

Assuming that the mass is not accelerating, the tension in the rope must be equal to the weight of the mass. The weight of the mass can be found using the formula:

weight = mass x acceleration due to gravity

where acceleration due to gravity is approximately 9.81 m/s².

Therefore, the weight of the mass is:

weight = 20 kg x 9.81 m/s² = 196.2 N

Since the mass is held stationary, the tension in the rope must be equal to the weight of the mass, which is 196.2 N. So the tension T in the rope is 196.2 N.

Answer:

Yes, lava is a liquid, that cools into rock, which is a solid.

The potential energy of the lemming when it lands is 0.9108672 J.

To determine the potential energy (PE) of the lemming when it lands, we need to consider the conservation of energy. The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height.

Given:

Mass of the lemming (m) = 0.0780 kg

Height of the cliff (h) = 5.36 m

First, let's calculate the potential energy when the lemming is on the cliff. Using the given formula, we have:

PE = mgh

PE = 0.0780 kg * 9.8 m/s² * 5.36 m

PE = 0.413616 J

Next, we need to determine the final kinetic energy of the lemming just before it lands. We can use the equation for kinetic energy (KE) given by KE = (1/2)mv², where v is the velocity of the lemming.

Given:

Velocity of the lemming (v) = 4.84 m/s

Calculating the kinetic energy, we have:

KE = (1/2) * 0.0780 kg * (4.84 m/s)²

KE = 0.9108672 J

According to the conservation of energy, the potential energy at the top of the cliff is equal to the kinetic energy just before landing.

No, density is not always uniform even when the cross sectional area is uniform and the potential difference across the conductor is maintained.

What is conductor?

A conductor is a material or device that allows electric current to pass through it. It is also used to transmit electric energy from one point to another. Conductors are commonly made of materials such as copper, aluminum, silver, and gold, and are used in electric circuits, wiring, and power grids. Conductors are essential for the transmission of electric power, and are used in a variety of applications, from electric motors and transformers to solar cells and electrical appliances. Conductors also act as a medium for transmitting electric signals, such as radio waves, and are used in telecommunications and broadcasting.

This is because density is a measure of the number of particles per unit volume, which can be affected by temperature and pressure. As the temperature or pressure changes, the number of particles contained in a given volume will also change. This means that even if the cross sectional area and potential difference across the conductor remain constant, the density of particles will not necessarily be uniform.

Yes, the force of the engine does work on the car as it accelerates the car forward. Work is defined as the transfer of energy that occurs when a force is applied over a distance, and in this case, the force of the engine is causing the car to move, so it is doing work.

As the car gains speed, its kinetic energy increases, which means it has more energy of motion. Kinetic energy is defined as one-half of the mass of an object times its velocity squared, so as the car's speed increases, so does its kinetic energy.

The gravitational potential energy of the car will remain constant as long as it stays on a horizontal road, assuming there is no change in elevation. Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, and since the car's position relative to the ground is not changing, its gravitational potential energy will remain constant.

The tractive force of the engine may change depending on the speed of the car and the resistance to motion that the car is encountering. As the car speeds up, the air resistance acting on the car will increase, which will require more force from the engine to maintain the same acceleration. Additionally, if the road surface is rough or there are inclines, the tractive force required to maintain the same speed or acceleration will also increase.

a.The direction of the magnetic field at point P, located above a long straight wire carrying current, is perpendicular to the wire and depends on the direction of the current, as determined by the right-hand rule, and b.the magnitude of the magnetic field at point P is 0.01 Tesla.

A magnetic field is a physical field that is created by electric charges in motion, such as an electric current or a moving magnet. It exerts a force on other moving charges and magnetic objects and is an essential component of many modern technologies including electric motors, generators, and magnetic storage devices.

a. Using the right-hand rule for the magnetic field around a straight wire, we can determine that the direction of the magnetic field at point P is perpendicular to both the direction of the current and the vector pointing from the wire to point P. Specifically, the magnetic field points out of the plane of the paper (or screen) if the current is flowing from left to right, and into the plane of the paper (or screen) if the current is flowing from right to left.

b. We can use the formula for the magnetic field around a straight wire to calculate the magnitude of the magnetic field at point P:

B = μ₀I/(2πr)

where B is the magnetic field, μ₀ is the vacuum permeability constant (4π x 10^-7 T m/A), I is current, and r is the distance from the wire to the point of interest. In this case, I = 50 A and r = 2.5 mm = 0.0025 m. Substituting these values into the formula, we get:

B = (4π x 10^-7 T m/A)(50 A)/(2π x 0.0025 m) ≈ 0.01 T

So, the magnitude of the magnetic field at point P is approximately 0.01 Tesla.

Therefore, According to the right-hand rule, the magnetic field at point P, which is placed above a long, straight wire carrying current, is perpendicular to the wire and depends on the direction of the current. Its strength is also 0.01 Tesla.

For the three-point charges fixed in a right triangle, we have:

1. The magnitude of the electric force on the +1.00 μC charge is 1.79 N.

2. The force does an angle of 21.68° with the x-axis.

First, let's denote the charges as is shown in the picture below:

The magnitude of the electric force on the charge 2 (+1.00 μC) is given by:  

\(|F_{net}| = \sqrt{(\Sigma\vec{F}_{x})^{2} + (\Sigma\vec{F}_{y})^{2}}\)  (1)    

Where:  

We can calculate the electrical forces with Coulomb's law:

\(\vec{F} = \frac{Kq_{1}q_{2}}{d^{2}}\)

Where:

Forces in the x-axis (\(\Sigma\vec{F}_{x}\))

The forces in the x-component are given by:

\(\Sigma\vec{F}_{x} = \vec{F}_{21}_{x} + \vec{F}_{23}_{x}\)

\(\Sigma\vec{F}_{x} = \vec{F}_{21}_{x}cos(\theta) + \vec{F}_{23}_{x}\)

\(\Sigma\vec{F}_{x} = \frac{Kq_{1}q_{2}}{d_{12}^{2}}cos(\theta) + \frac{Kq_{2}q_{3}}{d_{23}^{2}}\)   (2)

Where:              

We can calculate the angle θ with the following trigonometric function:

\(sin(\theta) = \frac{y}{z}\)

\(\theta = sin^{-1}(\frac{y}{z}) = sin^{-1}(\frac{8.10 cm}{9.60 cm}) = 57.5 ^\circ\)

To find the distance x (d₂₃), we need to use Pythagoras:

\(x = \sqrt{z^{2} - y^{2}} = \sqrt{(0.0960 m)^{2} - (0.0810 m)^{2}} = 0.051 m\)

After entering θ and x (d₂₃) into equation 2, we have:

\(\Sigma\vec{F}_{x} = \frac{9.00\cdot 10^{9} Nm^{2}C^{-2}(0.800 \cdot 10^{-6} C)(1.00 \cdot 10^{-6} C)}{(0.0960 m)^{2}}cos(57.5) + \frac{9.00 \cdot 10^{9}Nm^{2}C^{-2}(1.00 \cdot 10^{-6} C)(-0.600 \cdot 10^{-6} C)}{(0.051 m)^{2}}\)

\(\Sigma\vec{F}_{x} = [0.78*cos(57.5) + (-2.08) N] = -1.66 N\)

Hence, the x-component of the force is -1.66 N.

Forces in the y-axis (\(\Sigma\vec{F}_{y}\))

The only force acting on the y-axis is the y-component of the force F₂₁, so:

\(\Sigma\vec{F}_{y} = -\vec{F}_{21}_{y} = -\vec{F}_{21}sin(\theta)\)

The minus sign is because the vector is pointing in the negative y-direction (see the picture below).

\(\Sigma \vec{F}_{y} = -\frac{9.00\cdot 10^{9} Nm^{2}C^{-2}(0.800 \cdot 10^{-6} C)(1.00 \cdot 10^{-6} C)}{(0.0960 m)^{2}}sin(57.5) = -0.66 N\)

Hence, the y-component of the force is -0.66 N.

Finally, the magnitude of the electric force on the charge +1.00 μC is (eq 1):  

\(|F_{net}| = \sqrt{(-1.66 N)^{2} + (-0.66 N)^{2}} = 1.79 N\)                                  

Therefore, the magnitude of the electric force on the +1.00 μC charge is 1.79 N.

According to the picture below, the angle of the force with respect to the x-axis is given by:  

\(tan(\beta) = \frac{\Sigma\vec{F}_{y}}{\Sigma\vec{F}_{x}}\)

\(\beta = tan^{-1}(\frac{-0.66 N}{-1.66 N}) = 21.68 ^\circ\)

Therefore, the force does an angle of 21.68° with the x-axis.

Answer: a

Explanation:

Answer:

The correct answer is - option E. e. F1 > F2 and W1 = W2

Explanation:

Case 1 - F1 = mg, m= mass and g = gravitational force

Work done W1 = F1h= mgh (h - height of bed of truck)

Case 2 - F2 = mgsinθ

work done W2 = mgsinθ×L (L=length of ramp ans sin θ angle of ramp)

sinθ = h/l, then W2 = mg(h/L)L

W2 = mgh

By comparing both,

F2 = mgsinθ and F1 = mg therefore,

F2>F1

now, W2 = mgh, and W1 = mgh

therefore, W2 = W1.

If the coefficient of kinetic friction between Josh's sled and the snow is 0.08, he slides 6.97 meter from the base of the hill.

To find how far from the base of the hill Josh's sled ends up, we need to first find the speed of the sled at the bottom of the hill using the conservation of energy principle,

mgh = (1/2)mv², plugging in the values given in the problem, we get,

m(9.81 m/s²)(3.5 m) = (1/2)mv²

Simplifying and solving for v, we get,

v = √(2gh)

v = √(2(9.81 m/s²)(3.5 m))

v = 8.29 m/s

Now we can use the kinematic equation,

d = vt - (1/2)at, to find how far the sled slides on the horizontal patch of snow before coming to a stop, where d is the distance traveled, v is the initial velocity (8.29 m/s), a is the acceleration due to friction (-μg), and t is the time it takes to come to a stop (which we can find by setting v = 0 and solving for t),

0 = 8.29 m/s - μg*t

t = 8.29 m/s / μg

Substituting this value of t back into the kinematic equation, we get,

d = (8.29)(8.29/μg) - (1/2)μg(8.29/μg)²

d = 6.97 m

Therefore, Josh's sled ends up 6.97 meters from the base of the hill.
