Answer:
I=1A
Explanation:
In parallel combination voltage is same
In R1
V=IR
V=2×4
V=8V
In R2
V=IR
I=V/R
I=8/8
I=1A
I think it’s “light energy to chemical energy” let me know if i’m wrong
Answer:
If the force remains the same, the acceleration would decrease
Explanation:
According to Newton's second law, the acceleration of an object is given by

where
F is the force applied to the object
m is the mass of the object
As we see from the formula, the acceleration a is inversely proportional to the mass, m. Therefore, if the force F remains constant, this means that if the mass of the skateboarder increases, then the acceleration will decrease.
Answer:4.22 J
Explanation:
Given
mass of pitcher 
Force applied 
distance moved 
Applying work-Energy theorem which states that work done by all the forces is equal to the change in kinetic energy of the object
Work done by force 
W=
change in kinetic Energy =
