Answer:
As we know that heat given to a substance is given by the formula as
now we know that
now we know that aluminium and water both are of same mass and both are given same amount of heat so the value of Q and m will be same.
So here we can say that change in temperature depends inversely on the specific heat capacity.
So here if more specific heat capacity then there will be less change in temperature.
so we can conclude that since temperature of aluminium increases more so the specific heat capacity of aluminium will be less than that of water.
Answer:
Battery is the source of electrical energy which will help the charge to flow through a medium.
Battery is a constant source of potential difference which will create constant potential difference across the ends of a conductor where it is connected.
When a charge is passed through the constant potential difference then the change in electrostatic potential energy will give kinetic energy to the charge.
It is given as
so here charge will continuously flow through the conductor across which potential difference is applied by the battery. This constant motion or flow of charge is known as electric current.
What is the coefficient of kinetic friction between the block and the surface? Express your answer using two significant figures.
Answer:
0.39
Explanation:
Given information
m1=1.7 Kg
m2=0.011 Kg
v2=670 m/s
d=2.4 m
m2v2=(m1+m2)v hence and also
The deceleration due to friction is given by
therefore
Therefore,
related to the ratio of their frequencies.
One light beam has wavelength, λ1, and frequency, f1. Another light beam has wavelength, λ2, and frequency, f2. Write a proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio of their frequencies as λ1/ λ2 = f1/ f2.
The number of vibrations counted per second is called frequency. A wave is a group of vibrations that are referred to as energy. The bottom node is known as the crest, and the top node is known as the trough.
