The electric potential V in the space between two flat parallel plates 1 and 2 is given (in volts) by V = 1270x2, where x (in meters) is the perpendicular distance from plate 1. What is the magnitude and direction of the electric field at x = 3.5 cm? (Take the direction perpendicular to and away from plate 1 to be positive.)

Answer:

800 meters per hour

Explanation:

800 meters per hour is the average speed of an airplane that travels from New York to Los Angeles, a total distance of 4800 km, in 6.0 hours.

Force = 50N

Weight = Mass × Gravity = 25

Mass = 25 ÷ 10 = 2.5Kg

Time = 5 Seconds

we know

Force = mass × acceleration

50 = 2.5 × Velocity ÷ Time

50÷2.5 = Velocity ÷ 5

Velocity = 250 ÷ 2.5

Velocity = 100m/s.

Answer:

100m/s

Explanation:

force(f) = 50N

weight = 25N

weight = mass × gravity

25 = m × 10

25 = 10m

m = 25/10

m = 2.5kg

time(t) = 5sec

impulse formula

ft = m(∆v)

by substituting

50 × 5 = 2.5∆v

250 = 2.5∆v

∆v = 250/2.5

∆v = 100m/s

Explanation:

Answer: D. 6.1 m/s^2

Explanation:

Tbar = Tension of the Light Bar

Twire = Tension of the Wire

Newton First Law About Force :

Fx = 0

Tbar cos 45° - Twire cos 25° = 0

Twire = 0.78 Tbar ... (i)

Fy = 0

Tbar sin 45° - Twire sin 25° - 1 = 0 ... (ii)

Subtitute (i) into (ii) :

Tbar sin 45° - 0.78 Tbar sin 25° - 1 = 0

Tbar = 2.563 kN ... (iii)

Subtitute (iii) into (i) :

Twire = 0.78 (2.563)

Twire = 1.999 kN

His total displacement from his original position is -1 m

We know that total displacement of an object from a position x to a position x', d = final position - initial position.

d = x' - x

If we assume the lad's initial position in front of her house is x = 0 m. The lad then moves towards the positive x-axis, 5 m. He then ends up at x' = 5 m. He then finally goes back 6 m.

Since displacement = final position - initial position, and his displacement is d' = -6 m (since he moves in the negative x - direction or moves back) from his initial position of x' = 5 m.

His final position, x" after moving back 6 m is gotten from

x" - x' = -6 m

x" = -6 + x'

x" = -6 + 5

x" = -1 m

Thus, his total displacement from his original position is

d = final position - initial position

d = x" - x

d = -1 m - 0 m

d = -1 m

So, his total displacement from his original position is -1 m

Explanation: upward

For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.

Answer:

Explanation:

It must point upwards. How else would the ball begin to move up? What else is acting in such a way that the ball will go up?

There are only two forces acting on the ball

ANSWER:

3rd option

STEP-BY-STEP EXPLANATION:

First, let us consider block A:

By Newton's 2nd law of motion, force horizontal acting on the block A is given by F = m*a

As the block A and B, both are moving with constant velocity, the acceleration is zer .

Therefore:

F = m*a = 0

Then

uF = 0

There will be no horizontal force acting on block A

Now, considering block B:

STEP-BY-STEP EXPLANATION:

First, let us consider block A:

Making the same analogy as in block A in block B, we have the following (F = uF):

Given:

A coil and a magnet

To find:

What to do to induce a current into the coil

Explanation:

When the flux through a coil changes, the current is induced in it. To change the number of flux there should be a relative motion between the coil and the magnet.

Hence, to induce the electric current in a coil you can move a magnet into the center of the coil of the wire.

According to the law of conservation of momentum,

Where,

We need v2f

94 years x 365 days/year x 24 hours/day x 60 minutes/hour x 60 seconds/minute x 1.33 Watts = 2.4 GigaJoules (GJ)

Watts are a unit of power, measured in joules. It is a measure of the rate of energy transfer, or the amount of energy used in a given amount of time. Watts are typically used to measure the electrical power of an appliance, the power output of a motor, or the power being transmitted over a power line. Watts are often used to describe the rate of energy consumption for an appliance or device, such as a light bulb or a heater. The higher the wattage, the more power the appliance or device requires. Watts are also sometimes used to describe the power output of a generator, or the amount of energy produced by a solar panel.

Explanation:

The laws passed in the 1980s to reduce the use of chlorofluorocarbons (CFCs) were aimed at addressing the human-induced environmental change known as ozone depletion.

The laws passed in the 1980s to reduce the use of chlorofluorocarbons (CFCs) were aimed at addressing the human-induced environmental change known as ozone depletion. CFCs, which contain chlorine, were widely used in various applications such as aerosol propellants, refrigerants, and solvents. When released into the Earth's atmosphere, CFCs can reach the stratosphere and interact with ozone molecules, leading to the breakdown of ozone, which forms the protective ozone layer. The depletion of the ozone layer allows more harmful ultraviolet (UV) radiation from the Sun to reach the Earth's surface, posing risks to human health, ecosystems, and the environment. By reducing and eventually eliminating the use of CFCs, these laws aimed to mitigate the human-induced environmental change of ozone depletion and protect the ozone layer.

Determine the torque around this point created by each force acting on the wrist and select an axis to compute the torques about.

The forearm is the upper limb component that reaches from the shoulder to the wrist. Its bone structure is made up of the ulna and radius which are positioned laterally (medially).

The term "arm" most commonly refers to the entire upper limb appendage, although in anatomy, the phrase "forearm" is used to distinguish it from that.

As a result, the stress exerted by the bicep is 7.38 times more than the weight supported.

The formula for torque is Γ=r×F=rFsin(θ). Torque is, in additional observations, the cross product of the force vector & the distance vector, where a is the angle between r & F.

The complete queston is The amount of a radioactive element A at time t is given by the formula

A(t) = A₀e^kt

Answer:  A(t) =N e^( -1.2 X 10^-4t)

Explanation:

Given

Half life =  5730 years.

A(t) =A₀e ^kt

such that

A₀/ 2 =A₀e ^kt

Dividing both sides by A₀

1/2 = e ^kt

1/2 = e ^k(5730)

1/2 = e^5730K

In 1/2 =  5730K

k = 1n1/2 / 5730

k = 1n0.5 / 5730

K= -0.00012 = 1.2 X 10^-4

So that expressing   N in terms of t, we have

A(t) =A₀e ^kt

A₀ = N

A(t) =N e^ -1.2 X 10^-4t

The stretch of the spring is proportional to the weight of the mass hung from it. Since the spring stretches by 5.9 cm when a 1.6 kg mass is hung from it, we can use this information to find the stretch when a 2.1 kg mass is hung from it.

The stretch of the spring is given by:

stretch = (mass x gravity x length) / (spring constant)

where mass is the mass hung from the spring, gravity is the acceleration due to gravity (9.81 m/s^2), length is the stretch of the spring, and the spring constant is a measure of the stiffness of the spring (measured in N/m).

We can rearrange this equation to solve for the stretch of the spring:

stretch = (mass x gravity x length) / (spring constant)

length = (spring constant x stretch) / (mass x gravity)

Substituting the given values, we get:

length = (spring constant x 0.059 m) / (1.6 kg x 9.81 m/s^2)

Simplifying, we get:

length = 0.236 m

Therefore, the stretch of the spring when a 2.1 kg mass is hung from it is 0.236 m.
