Answer:
c. Light energy to thermal energy
Explanation:
The energy from the sun comes in the form of light energy but is converted to thermal energy.
Answer: No
Explanation:
The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
The momentum of a moving object is given by:

where m is the mass of the object and v its speed.
In this problem, the ball has a mass of

and its momentum is

, so we can rearrange the previous equation to find the speed of the ball:

1. Calculate the equivalent resistance in the circuit :
In the given diagram, the resistors are in series connection,
So equivalent resistance = sum of resistance of both resistors.

Therefore, Equivalent resistance = 840 ohms.
2. Calculate the current through the battery :

Hence, current through the battery = 0.142 A
3. How much current is passing through each resistor :
Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.
