Answer:
The 3rd graph
Explanation:
A free body diagram is a diagram which shows all the forces acting on an object.
The problem asks us to find the free body diagram of block A, so we must find all the forces acting on block A.
We have 3 forces acting on block A in total:
- The force of gravity (its weight), which pushes the block downward (in the diagram, it is the force represented with 
- The tension in the rope 1, which pulls block A upwards: this force is represented with 
- The tension in the rope 2, due to the weight of block 2, which pulls block A downwards: this force is represented with 
Based on the direction of these 3 forces, the correct diagram is the 3rd one.
Answer:
B)
Explanation:
Negative (-) charge M will not move towards negative (-) charge K because, same charges will not attract each other in the given case
Negative (-) charge at the M tends to move towards positive (+) charge L in the direction of B) because opposite charges attract each other.
Answer:
The answer is below
Explanation:
Charles law states that the volume and temperature of a fixed amount of a gas is directly proportional to each other provided that pressure is held constant.
Boyle's law states that the volume and pressure of a fixed amount of a gas are inversely proportional to each other provided that temperature is held constant.
a) Constant property:
In Charles law, pressure is kept constant while in Boyle's law, temperature is held constant.
b) Varying properties:
In Charles law, volume and temperature are varying while in Boyle's law, pressure and volume are varying.
c) Type of variance:
In Charles law we have a direct variance while in Boyle's law we have an indirect variance.
d) Charles law is given as:
Boyle's law is given as:
Let’s use *queue dramatic voice* THE GREAT LAW OF THE CONSERVATION OF MOMENTUM!!!!!
m1v1i + m2v2i = m1v1f + m2v2f
m1v1i - m1v1f = m2(v2f - v2i)
m2 = (m1v1i - m1v1f) / (v2f - v2i)
m2 = [(0.15)(15) - (0.15)(1.2)] / (13 - -22)
Henceforth, my good sire, the mass indeed works out to a fine approximate value of:
m = 0.06 kg
That’s a pretty small tennis ball!
