Answer:
lesser time
Explanation:
The latent heat of fusion is defined as the amount of heat required to convert 1 gram of water into 1 gram of ice at constant temperature called melting point.
In this situation only the state of matter is changed, the temperature of the substance remains constant.
A liquid has lower latent heat rather than water, it means it requires lesser amount of heat to fuse it , so it requires lesser amount of time to melt the ice made by this liquid.
So, it requires lesser time.
Answer:
- Decreasing the resistance
- Using a shorter length
- Using a smaller area wire
Explanation:
Formula for conductance in wires is;
G = 1/R
Where;
G is conductance
R is resistance
This means that increasing the resistance leads to a larger denominator and thus a smaller conductance but to decrease the denominator means larger conductance.
Thus, to increase the conductance, we have to decrease the resistance.
Resistance here has a formula of;
R = ρL/A
Where;
ρ is resistivity
L is length of wire
A is area
Thus, to decrease the resistance, we will have to use a shorter length and smaller area of wire.
Answer:
b. The spring is neither stretched nor compressed.
Explanation:
As we know that the equilibrium position is defined as the position where net Force is zero on the system
so here we can say that
now we know that the spring block system is oscillating on the smooth floor so here we can say that there are only three forces on the block
1) Normal force
2) Weight
3) Spring force
since normal force is counter balanced by the weight of the object
so here only spring force will be there in horizontal direction.
So at equilibrium position we can say that net horizontal force will be zero
So we can say that
b. The spring is neither stretched nor compressed.
Answer:
Hey
I have no idea what "die hele" means.
Kinetic energy is the energy an object has due to its MOTION.
