Answer:9.82 m
Explanation:
As we know from equation of motion
S=v*t +0.5 a t^2
Know s=H/2
a =9.82
t=1
V=0
Plugging the values
H*0.5=0+0.5*9.82*1^2
H=9.82 m
Answer: An object at rest has no kinetic energy, but it may have potential energy resulting from its location or structure.
Explanation: To find the answer, we need to know more about the kinetic and potential energies.
<h3>What is kinetic energy of a body?</h3>
- Kinetic energy is a form of mechanical energy possessed by a body by virtue of its motion.
- Kinetic energy of a body of mass m moving with a velocity v is given by,
<h3>What is potential energy?</h3>
- Potential energy is a form of mechanical energy possessed by a body by virtue of its position in the field or configuration.
- PE is always associated with a conservative force.
- There cannot be potential energy due to frictional or viscous forces.
Thus, we can conclude that, an object at rest has no kinetic energy, but it may have potential energy resulting from its location or structure.

Body composition refers to the amount of fat and muscle that the body has. ... Muscular strength is the amount of force a muscle or group of muscles can exert. true. Muscular endurance is fueled by anaerobic energy.
Flux through each of the six faces of the cube:
Explanation:
In this problem, a charge is placed at the center of the cube.
We can apply Gauss Law, which states that the flux through the surface of the cube is equal to the charge contained within the cube divided by the vacuum permittivity; mathematically:
where
is the charge
is the vacuum permittivity
Here we want to find the flux through each of the six faces of the cube.
By simmetry, we can say that the 6 faces are identical: therefore, the flux through each of them must be the same. This means that the flux through each faces is 1/6 of the total flux through the total surface, therefore:

Answer:
Explanation:
Energy = volt x charge
= 12 x 750000 J
= 9000,000 J
Latent heat of vaporisation
= 2260000 J / kg
kg of water vaporised
= 9000,000 / 2260000
= 3.982 kg .
