Calculate the potential energy of a 5 kg object sitting at the top of a 2 meter ramp.

1 answer:

5 0

The formula used to find potential energy is P.E. = M * G * H (P.E. is potential energy, M is mass, G is gravitational pull, and H is height). So the answer to your question is 5 * 9.8 * 2, which equals 98.

Wave 1 carries more energy than Wave 2. Wave 3 carries more energy than Wave 2. Keeping speed constant, the greatest amount of e

inn [45]

Answer:

The greatest amount of energy is carried by a wave with the largest frequency.

Explanation:

velocity= frequency X wavelength

If the three waves moves with the same t the speed of light, then those with the largest frequency have more energy.

That is to say, a wave with a higher frequency and a lower wavelength will have the highest energy.

What is the magnetic field at the center of a circular loop

Elan Coil [88]

Answer:

The magnetic field at the center of a circular loop is $3.14\times10^{-5}\ T$ .

Explanation:

Given that,

Radius = 4.0 cm

Current = 2.0 A

We need to calculate the magnetic field at the center of a circular loop

Using formula of magnetic field

$B = \dfrac{I\mu_{0}}{2r}$

Where, I = current

r = radius

Put the value into the formula

$B =\dfrac{2.0\times4\pi\times10^{-7}}{2\times4.0\times10^{-2}}$

$B =0.00003141\ T$

$B=3.14\times10^{-5}\ T$

Hence, The magnetic field at the center of a circular loop is $3.14\times10^{-5}\ T$ .

Several forces act on an object at rest. It is known that the sum of the forces acting on the object is zero. Which statement is

MAVERICK [17]

Answer:

When net force of zero acting on a ball which is at rest , then the object center of mass will not accelerate , but the object may begin to rotate .

Explanation:

Here when there is an object where several forces are acing upon are zero then the center of mass will not accelerate because we know that

$A_{com}=\frac{F_{net}}{M}$

Where $A_{com} =$ acceleration of center of mass

$F_{net}$ = net force = 0

So the acceleration of center of mass will be zero

But the torque ,may not be zero as torque is product of individual force and perpendicular force .

Since if torque is not equal to zero then the object may begin to rotate
