Answer:
a)
b)S= 46.4 cm
Explanation:
Given that
Velocity = 16 Km/s
V= 16,000 m/s
E= 27 mV/m
E=0.027 V/m
d= 22.5 cm
d= 0.225 m
a)
lets time taken by electron is t
d = V x t
0.225 = 16,000 t
b)
We know that
F = m a = E q ------------1
Mass of electron ,m
Charge on electron
So now by putting the values in equation 1
Here initial velocity u= 0 m/s
S=0.464 m
S= 46.4 cm
S is the deflection of electron.
Explanation:
this is the ans hope it works
Power in physics is work done over time. So the answer is Power is the rate at which work is done.
Answer:
c. frequency
Explanation:
Frequency refers to t<u>he flow at which a vibration develops into a wave</u>. Moreover, frequency is typically measured per second, and it can occur in a material like sound waves or in an electromagnetic field, such as radio waves and light. As a result, the sound mixer can exclude unwanted vibrations that turn into sound waves.
Answer:
Endothermic, because energy is absorbed (A)
Explanation:
The reaction that take place in the instant cold pack causes the surroundings around it, including the bag that contains it. When the bag loses heat to the cold pack, the cold pack absorbs the heat, thereby causing the environment (the bag) to be cold.
