Answer:
Space
Explanation:
Solar energy is energy from the Sun. This energy is in form of radiation heat and light. When solar energy reaches a surface it bounces off. This is because they are radiation waves.
By using the Plancks-Einstein equation, we can find the energy;
E = hf
where h is the plancks constant = 6.63 x 10⁻³⁴
f = frequency = 3.55 x 10¹⁷hz
E = (6.63 x 10⁻³⁴) x (3.55 x 10¹⁷)
E = 2.354 x 10⁻¹⁶J
Answer:
A. Electric potential energy into kinetic energy
Explanation:
The electric potential energy of the charged particles is converted into kinetic energy as the electron is released.
Answer:
Explanation:
information we have:
mass: 
lenght: 
frequency: 
time: 
and from the information we have we can calculate the angular velocity 
. which is defined as
----------------------------
Now, to calculate the torque
We use the formula
where 
is the moment of inertia and 
is the angular acceleration
moment of inertia of a uniform rod about the end of it:
substituting known values:
for the torque we also need the acceleration which is defined as:
susbtituting known values:
and finally we substitute and into the torque equation :
Answer:
For the first one it would be screw and for the second one it is a ramp
