Answer:
The rate of change of displacement is called velocity.
Explanation:
How fast an object travels
Answer:
101397.16 pa
Explanation:
The pressure recorded will be equal to pgh
Where p = density of mercury = 13.6x10^3 kg/m^ 3
g = acceleration due to gravity 9.81 m/s^2
h = height of mercury in the column = 760 mm = 760x10^-3 m
Pressure = 13.6x10^3 x 9.81 x 760x10^-3 = 101397.16 pa
<span>The sun is currently a hot ball of glowing gases that is considered as a star. It is the center of our solar system. Its power is responsible for bringing life to this planet and it also affects the orbits of distant planets like Neptune and Pluto. Without it, Earth will not have the capacity to sustain life and maintain its balance.<span>

Answer:
b. A voltage causes electric charges to move from lower to a higher potential.
Explanation:
As we know, current flows from high voltage to low voltage and the electric charge flows opposite to the direction of the current. That is why we can say that the electric charge flows from low voltage to high voltage.
Resistance does not cause the electron to flow from low voltage to high voltage.
Therefore the answer is b.
The equation to be used to
calculate the heat release when solid melts is the enthalpy of melting. It is
represented as H
= mCpT where H is the heat
released after phase change, m is the mass of the substance, Cp is the specific
heat capacity of the substance and T
is the change in temperature.
