Answer:
900kJ
Explanation:
Work done hereis lifting that water mass on to the surface level
v = volume of the tank
d= density of water (1000kg/m3)
g = gravotational acceleration
workdone=Weight * distance
= (v*d*g)*distance
=
Answer:
The Sun’s magnetic field, solar winds and the Earth's magnetic tail are responsible for making the aurora lights in the north and south poles look different, say international scientists. Researching the interactions of these phenomena have debunked previous theories around why the lights can have different shapes and can occur in different locations. This research also helps scientists to better understand the interactions between the sun and earth, which could help with predicting space weather.

Answer:
1.1655 N
Explanation:
Given that,
Initial speed, u = 25 m/s
Final speed, v = 26 m/s
Time taken, t = 54 s
So, Applying equation of motion as:

According to the Newton's second law of motion:-

Mass = 63 kg
So,

<u>Force = 1.1655 N</u>
Answer:As a noun relative means a person who is connected with others by blood.
