Answer:
66.24 Volts
Explanation:
W = Amount of work done in moving the charge from negative to positive terminal = 2.186 J
Q = Amount of charge being moved from negative to positive charge = 0.033 C
ΔV = EMF of the battery
Amount of work done in moving the charge from negative to positive terminal is given as
W = Q ΔV
2.186 = (0.033) ΔV
ΔV = 66.24 Volts
Answer:
the particle arrangement in liquid are close together with no regular arrangement
Answer:
Wave X has a shorter wavelength.
Explanation:
The relation between the speed of a wave, its wavelength and frequency is given by :
It can be seen that the relationship between the frequency and wavelength is inverse.
In this problem, it is mentioned that two sound waves (wave X and wave Y) are moving through a medium at the same speed. The frequency of wave X is greater than wave Y. Then it would mean that wave X have shorter wavelength than wave Y (due to inverse relation).
Answer:
3.59 m/s
Explanation:
We are given that
Mass of lineman,m=85 kg
Mass of receiver,m'=90 kg
Speed of receiver,v'=5.8 m/s
Speed of lineman,v=4.1 m/s
We have to find the their velocity immediately after the tackle.
Initial momentum,
According to law of conservation of momentum
Initial momentum=Final momentum=
