Answer:
i think its because u gave the almost every answer the same exact thing. all the questions have different ways of moving which means different forces for each one i hope this helps :)
Explanation:
Given mass = 2kg, height = 10m,g = 9.8.
We know that Work done W = FD
= > W = (mg)(D)
= > W = (2 * 9.8)(10)
= > W = 196 Joules.
Hope this helps!
Answer:
2000 V/m
1778021.69323 m/s
Explanation:
V = Voltage = 9 V = 
q = Charge of proton = 
m = Mass of electron = 
v = Velocity of electron
Electric field is given by

The electric field is 2000 V/m
Here, the energy of the system is conserved

The velocity of the electron is 1778021.69323 m/s
Answer:
A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar aureole to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. This narrow track is called the path of totality.
A partial lunar eclipse happens when part of the Moon enters Earth's shadow. In a partial eclipse, Earth's shadow appears very dark on the side of the Moon facing Earth.
