If an object is changing its direction or the speed of the object is changing then the object is said to be accelerating.

Acceleration is the rate at which speed and direction of velocity change over time. A point or object moving straight ahead is accelerated when it accelerates or decelerates. Even though the speed is constant, motion on a circle accelerates because the direction is constantly shifting.

An object is said to be accelerating if its velocity is changing, whether the change in velocity is constant or varies by a fixed amount.

Since acceleration is a vector quantity—which means it has both a magnitude and a direction—it follows that an object is said to be accelerating if its direction is changing.

Explanation:

Atom A has 10 protons, 12 neutrons, and 10 electrons, while Atom B has 10 protons, 10 neutrons, and 12 electrons.

Atom A and Atom B are not isotopes of each other. Isotopes are atoms of the same element that differ in the number of neutrons but have the same number of protons. In this case, Atom A and Atom B have different numbers of protons, which means they are not isotopes of each other.

The number of protons determines the element, and since Atom A and Atom B have different numbers of protons, they belong to different elements.

Isotopes, on the other hand, have the same number of protons but differ in the number of neutrons.

This variation in the number of neutrons gives isotopes different atomic masses while retaining the same chemical properties.

However, Atom A and Atom B do not fulfill this criterion, so they cannot be considered isotopes of each other.

Answer:

v = 0.059 m/s

Explanation:

To find the final speed of Olaf and the ball you use the conservation momentum law. The momentum of Olaf and the ball before catches the ball is the same of the momentum of Olaf and the ball after. Then, you have:

\(mv_{1i}+Mv_{2i}=(m+M)v\)  (1)

m: mass of the ball = 0.400kg

M: mass of Olaf = 75.0 kg

v1i: initial velocity of the ball = 11.3m/s

v2i: initial velocity of Olaf = 0m/s

v: final velocity of Olaf and the ball

You solve the equation (1) for v and replace the values of all variables:

\(v=\frac{mv_{1i}}{m+M}=\frac{(0.400kg)(11.3m/s)}{0.400kg+75.0kg}=0.059\frac{m}{s}\)

Hence, after Olaf catches the ball, the velocity of Olaf and the ball is 0.059m/s

Answer:

The average induced emf in the loop is 0.3 V

Explanation:

Given:

d = 22 cm

Magnetic field  is  B = 1.5 T

Change in time  Δt = 0.20 sec.

Radius of loop  = r = d/2 = 11 x \(10^{-2}\) m

where Ф = magnetic flux

Ф = BAcos0   (in this occasion, Ф=0)

where area A = pi * r²

note that we have to neglect negative sign due to its lenz law...so

       B * pi * r

e = ----------------

Answer:

The maximum length of the train is 110 m

Explanation:

Speed

It's the rate of change of the distance traveled by a moving object. Given the distance d and the time t it takes to complete it, the speed is calculated as follows:

\(\displaystyle v=\frac{d}{t}\)

The train spotter starts seeing the train that moves at v=22 m/s for 5 seconds until it completely passes him.

The maximum length of the train is the distance traveled, which can be calculated by solving the formula for d:

d = vt

d = 22 m/s * 5 s

d = 110 m

The maximum length of the train is 110 m

The potential energy of the shot as it left the hand relative to the ground would be -524 J.

At the moment the shot putter releases the shot, the total energy of the system is:

E = KE + PE

where KE is the kinetic energy of the shot and PE is its potential energy relative to the ground. We can assume that the kinetic energy is entirely due to the motion of the shot in the horizontal direction, so we can write:

KE = (1/2)mv^2

where m is the mass of the shot, and v is its horizontal velocity. Substituting the known values, we get:

KE = (1/2)(5.00 kg)(15.0 m/s)^2 = 1125 J

At the maximum height of 14.5 m, the shot has zero kinetic energy, so all its energy is potential energy:

PE = mgh

where g is the acceleration due to gravity and h is the height above the ground. Substituting the known values, we get:

PE = (5.00 kg)(9.81 m/s^2)(14.5 m - 3.00 m) = 601 J

Therefore, the potential energy of the shot as it left the hand relative to the ground was:

PE = E - KE = 601 J - 1125 J = -524 J

Answer:

the energy possessed by a body due to its motion or position is called mechanical engergy

Answer:

We must be approximately at least 1.337 meters away to be exposed to an intensity considered to be safe.

Explanation:

Let suppose that intensity is distributed uniformly in a spherical configuration. By dimensional analysis, we get that intensity is defined by:

\(I = \frac{\dot W}{\frac{4\pi}{3}\cdot r^{3}}\) (1)

Where:

\(I\) - Intensity, measured in watts per square meter.

\(r\) - Radius, measured in meters.

If we know that \(\dot W = 10\,W\) and \(I = 1\,\frac{W}{m^{2}}\), then the radius is:

\(r^{3} = \frac{\dot W}{\frac{4\pi}{3}\cdot I }\)

\(r = \sqrt[3]{\frac{3\cdot \dot W}{4\pi\cdot I} }\)

\(r = \sqrt[3]{\frac{3\cdot (10\,W)}{4\pi\cdot \left(1\,\frac{W}{m^{2}} \right)} }\)

\(r \approx 1.337\,m\)

We must be approximately at least 1.337 meters away to be exposed to an intensity considered to be safe.

Answer:

Explanation:

Convert all lengths to meters:

Refer to the diagram attached (not to scale.) Assuming that the screen is parallel to the line joining the two slits. The following two angles are alternate interior angles and should be equal to each other:

These two angles are marked with two grey sectors on the attached diagram. Let the value of these two angles be \(\theta\).

The path difference between the two beams is approximately equal to the length of the segment highlighted in green. In order to produce the first dark fringe from the center of the screen (the first minimum,) the length of that segment should be \(\lambda / 2\) (one-half the wavelength of the light.)

Therefore:

\(\displaystyle \cos \theta \approx \frac{\text{Path difference}}{\text{Slit separation}} = \frac{\lambda / 2}{3.00\times 10^{-5}\; \rm m}\).

On the other hand:

\(\begin{aligned} \cot \theta &\approx \frac{\text{Distance between central peak and first minimum}}{\text{Distance between the screen and the slits}} \\ &= \frac{3.70\times 10^{-2}\; \rm m}{5.20\; \rm m} \approx 0.00711538\end{aligned}\).

Because the cotangent of \(\theta\) is very close to zero,

\(\cos \theta \approx \cot \theta \approx 0.00711538\).

\(\displaystyle \frac{\lambda /2}{3.00\times 10^{-5}\; \rm m} \approx \cos\theta\approx 0.00711538\).

\(\begin{aligned}\lambda &\approx 2\times 0.00711538 \times \left(3.00\times 10^{-5}\; \rm m\right) \\ &\approx 4.26 \times 10^{-7}\; \rm m = 426\; \rm nm\end{aligned}\).

If the path difference is increased by one wavelength, then the intersection of the two beams would move from one bright fringe to the next one.

On the other hand, if the distance between the maximum and the center of the screen is much smaller than the distance between the screen and the filter, then:

\(\begin{aligned}&\frac{\text{Distance between image and center of screen}}{\text{Distance between the screen and the slits}} \\ &\approx \cot \theta \\ &\approx \cos \theta \\ &\approx \frac{\text{Path difference}}{\text{Slit separation}}\end{aligned}\).

Under that assumption, the distance between the maximum and the center of the screen is approximately proportional to the path difference. The distance between the image (the first minimum) and the center of the screen is \(3.70\; \rm cm\) when the path difference is \(\lambda / 2\). The path difference required for the first maximum is twice as much as that. Therefore, the distance between the first maximum and the center of the screen would be twice the difference between the first minimum and the center of the screen: \(2 \times 3.70\; \rm cm = 7.40\; \rm cm\).

Widening the prism adds additional glass, which slows light down even further and increases the amount of refraction.

The angles and plane sides of a prism cause light to be bent, or refracted, when it flows through them; the degree of refractive distortion varies somewhat depending on the wavelength of light.

When light travels from the air to the prism's glass, its speed changes, causing the light to bend and shift course. Once light enters the prism, it bends because the refraction indices of the air and glass differ. The light exits the prism bent even more since the sides are slanted.

According to Newton's Law of Gravitation, the gravitational force between two objects is always mutual, meaning that the force that one object exerts on the other is equal in magnitude but opposite in direction.

This means that if planet A exerts a gravitational force on planet B, then planet B will also exert a gravitational force on planet A. The magnitude of this force will be equal to the magnitude of the force that planet A exerts on planet B, but the direction will be opposite.

For example, if planet A exerts a gravitational force on planet B that is pulling planet B towards planet A, then planet B will also exert a gravitational force on planet A that is pulling planet A towards planet B. The magnitude of these two forces will be equal, but the directions will be opposite.
