A cart is loaded with a brick and pulled at constant speed along an inclined plane to the height of a seat-top. If the mass of t

he loaded cart is 3.0 kg and the height of the seat top is 0.45 meters, then what is the potential energy of the loaded cart at the height of the seat-top?

Answer:

13.23J

Explanation:

PE = m*g*h

PE = (3 kg ) * (9.8 m/s/s) * (0.45 m)

What is the significance of the fact that the gravitational constant, G, is a very small number and that Coulomb’s constant, k,
WITCHER [35]

The comparison indicates that the gravitational force is a much weaker force than the electromagnetic force. This is the significance of the fact that the gravitational constant, G, is a very small number and that Coulomb’s constant, k, is a very large number

Answer: The comparison indicates that the gravitational force is a much weaker force than the electromagnetic force.

<u>Explanation: </u>

We know that the universal formula for the estimation of gravitational force is,

                       F=G \times\left(\frac{m_{1} \times m_{2}}{r^{2}}\right)

Where,

F, Gravitational force, m_{1} \text { and } m_{2}- objects masses r- The relative distance between the two objects  

G, Gravitational Constant 6.67 \times 10^{-11} \frac{N m^{2}}{k g^{2}}

And, the electrostatic force between two scalar charges according to the Coulomb’s law is,

                  F=k \times\left(\frac{q_{1} \times q_{2}}{r^{2}}\right)

F, Electrostatic force between two charges,q_{1} \text { and } q_{2}- Two scalar charges, r - The relative distance between two scalar charges, k- Coulomb’s constant 8.987 \times 10^{9} \frac{N m^{2}}{c^{2}}

Now, on comparing the values of G and k, we can easily evaluate that eventually, the gravitational force will be lesser than the coulomb’s force.  

Besides this, we can also judge this fact through various examples such as, a balloon rubbed with a cloth, easily sticks to the wall for some time. Opposing the gravitational force of the Earth which is not the case with the normal balloon.

It drops without having the electrostatic force between the wall and the balloon.  This shows that the gravitational force draws lesser impact on objects as compared to the electrostatic force.

What is the unit for measuring energy
sdas [7]
This would be called a Joule. The formula for energy is <span>P.E. = mgh (otherwise known as the gravitational force formula, which is energy.) M is the mass in kilograms, and G is the acceleration due to gravity, which is actually (9.</span>8 m / s2<span> at the surface of the earth.) I hope this helps! ~Mia</span>

Where is the Long Head located?<br> Outside of the Arm<br> Inside of the Arm<br> On the Shoulder
Basile [38]

Answer:

The biceps muscle is located at the front of your upper arm. The muscle has two tendons that attach it to the bones of the scapula bone of the shoulder and one tendon that attaches to the radius bone at the elbow. The tendons are tough strips of tissue that connect muscles to bones and allow us to move our limbs.
