This question involves the concepts of work done and the frictional force.

a. Work done by the person is "692.82 N".

b. Work done by the frictional force is "490.5 N".

a.

Work done by the person can be given by the following formula:

\(W=FdCos\theta\)

where,

W = work done by the person = ?

F = Force applied by the person = 80 N

d = distance traveled = 10 m

θ = angle between force and motion = 30°

Therefore,

\(W=(80\ N)(10\ m)Cos30^o\)

W = 692.82 N

b.

Work done by the frictional force is given by the following formula:

\(W_f=fd\\W_f=\mu mgd\)

where,

\(W_f\) = work done by the frictional force = ?

μ = coefficient of friction = 0.5

g = acceleration due to gravity = 9.81 m/s²

Therefore,

\(W_f=(0.5)(10\ kg)(9.81\ m/s^2)(10\ m)\)

\(W_f=490.5\ N\)

Using the formula F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them, we can calculate the gravitational force between Jupiter and the sun.

Plugging in the values, we get:

F = (6.674 x 10^-11 N * (m^2 / kg^2)) * ((1.9 x 10^27 kg) * (2 x 10^30 kg)) / (78 x 10^6 m)^2

Simplifying this, we get:

F = 1.98 x 10^27 N

Therefore, the gravitational force between Jupiter and the sun is approximately 1.98 x 10^27 Newtons.

The gravitational force between Jupiter and the sun, calculated using Newton's law of gravitation with their masses and distance, is \(1.95 * 10^{22} N.\)

Answer:

C. Taste aversion can develop after only one pairing of a stimulus and response.

Explanation:

Taste aversion is a unique type of learned response where an individual develops a strong aversion or avoidance to a specific taste or food after a single pairing of that taste with a negative reaction, such as nausea or illness. This is in contrast to traditional conditioning, where multiple pairings of a stimulus and response are typically required for learning to occur. Taste aversion demonstrates a unique rapidity and specificity in its development, which deviates from the general principles of conditioning.

Answer:

306.08 kPa

Explanation:

Given data

Average stress of first wave = 3811 kPa

amplitude of first wave ( A1 ) = 430 kPa

Frequency of first wave = 6 Hz

Determine the average stress of the second sinusoidal component in kPa

Amplitude of the additional wave (A2add) = \(\frac{A1}{2}\)  =  430 / 2 = 215 kPa

next we will determine the resultant amplitude of the second wave

A2 = \(\sqrt{A^{2} _{1} } + A^{2} _{2add} + 2A_{1}A_{2add} Cos\alpha\)

     = \(\sqrt{430^2+ 215^2 + 2(430*215) * cos 90}\)

     = \(\sqrt{184900 + 46225 }\)

     = \(\sqrt{231155}\)  = 480.79

hence the average stress of the second sinusoidal component

= \(\frac{2A_{2} }{\pi }\)

=  \(\frac{2 * 480.79 }{\pi }\)  =  306.08 kPa

C. The average acceleration is positive and smaller in magnitude than the initial acceleration.

Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.

a = Δv/Δt

where;

a = (250 - 248) / (70 - 40)

a = 0.067 m/s²

Thus, we can conclude that the average acceleration is positive and smaller in magnitude than the initial acceleration.

Answer:

The common speed is 1.95 m/s

Explanation:

Law Of Conservation Of Linear Momentum

It states that the total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and velocity v is  

P=mv.  

If we have a system of bodies, then the total momentum is the sum of all of them:

\(P=m_1v_1+m_2v_2+...+m_nv_n\)

If a collision occurs, the velocities change to v' and the final momentum is:

\(P'=m_1v'_1+m_2v'_2+...+m_nv'_n\)

In a system of two masses, the law of conservation of linear momentum

is written as:

\(m_1v_1+m_2v_2=m_1v'_1+m_2v'_2\)

If both masses stick together after the collision at a common speed v', then:

\(m_1v_1+m_2v_2=(m_1+m_2)v'\)

The common velocity after this situation is:

\(\displaystyle v'=\frac{m_1v_1+m_2v_2}{m_1+m_2}\)

The truck of m1=1200 N (weight) travels at v1=2 m/s and hits a stationary mass (v2=0) of m2=30 N (weight). After the bodies collide, they keep moving together. Before we can calculate the common speed, we need to calculate the masses of the bodies, since they are given as weights.

\(m_1=\frac{P_1}{g}=\frac{1200}{9.8}=122.45 Kg\)

\(m_2=\frac{P_2}{g}=\frac{30}{9.8}=3.06 Kg\)

Now calculate the common speed:

\(\displaystyle v'=\frac{122.45 * 2+3.06 * 0}{122.45+3.06}\)

\(\displaystyle v'=\frac{244.9}{125.51}=1.95\ m/s\)

The common speed is 1.95 m/s

The charger's speed is 76.08 miles/h if the Dodge Charger goes speeding past Berkmar High School at 2:30 PM. If it travels 170 m in 5.0 s.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

It is given that:

A Dodge Charger goes speeding past Berkmar High School at 2:30 PM. If it travels 170 m in 5.0 s.

As we know,

Speed = distance/time

The unit conversion can be defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

170 meters =  0.10563 miles

5 seconds = 0.0833 minutes

0.0833 minutes = 1.388×10⁻³ hours

Speed = 0.10563 miles/1.388×10⁻³ hours

Speed = 76.08 miles/h

Answer

The motion of an object is relative to either the frame of reference of the observer, or to another distinct frame of reference.

All motion is relative because every object at rest is also in motion and every object motion is in rest and these both term are related to each other... and these all depends on reference point.

for example : the car at rest is in motion with respect to earth motion

Capacitance is the ability of an object or device to store an electric charge. It is measured by the change in charge in response to a potential difference and is expressed as a ratio of these quantities.

For charge:

Q = CV

Where Q = Charge

C = Capacitance (45 μF or 45 × 10⁻⁶ F)

V = Voltage applied (100 V)

Q = 45 × 10⁻⁶ × 100

Q = 45 × 10⁻⁴ C

For angular frequency:

ν = 1/√(LC)

ν = angular frequency

L = Inductance (45 mH or 45 × 10⁻³ H)

C = Capacitance (45 μF or 45 × 10⁻⁶ F)

ν =  1/√(45 × 10⁻³ × 45 × 10⁻⁶ )

ν =  1/4.5 × 10⁻⁵

ν =  0.22 × 10⁵ H or 22 × 10³ H

For the period of electric oscillation:

t = 1/ν

t = period of electric oscillation

ν = angular frequency (22 × 10³ H)

t = 1/22 × 10³

t = 4.5 × 10⁻⁵ sec

Now, for current:

Q = It

I = Q/t

I = current

Q = Charge (45 × 10⁻⁴ C)

t = time (4.5 × 10⁻⁵ sec)

I = 45 × 10⁻⁴ / 4.5 × 10⁻⁵

I = 1 A

If the time is 2.9 ms, then charge and current will be

Q = It

Q = 1 × 2.9 × 10⁻³

Q = 2.9 × 10⁻³ C

I = Q/t

I = 2.9 × 10⁻³/2.9 × 10⁻³

I = 1 A

The diameter of the smaller end of the pipe is approximately 0.78 meters.

To determine the diameter of the smaller end of the pipe, we can use the principle of conservation of mass. According to this principle, the mass flow rate of water should remain constant throughout the pipe.

The mass flow rate is given by the equation:
Mass flow rate = density of water * cross-sectional area * velocity

Since the density of the water remains constant, we can write:
Cross-sectional area1 * velocity1 = Cross-sectional area2 * velocity2

Given that the velocity1 is 13 m/s, the diameter1 is 1.2 m, and the velocity2 is 30 m/s, we can solve for the diameter2 using the equation:
(pi * (diameter1/2)^2) * velocity1 = (pi * (diameter2/2)^2) * velocity2

Simplifying the equation:
(1.2/2)^2 * 13 = (diameter2/2)^2 * 30

Calculating the equation:
(0.6)^2 * 13 = (diameter2/2)^2 * 30

0.36 * 13 = (diameter2/2)^2 * 30

4.68 = (diameter2/2)^2 * 30

Dividing both sides by 30:
0.156 = (diameter2/2)^2

Taking the square root of both sides:
0.39 = diameter2/2
