Answer:
The coefficient of static friction between your partner and the floor is 0.55
Explanation:
Given:
Mass 
Kg
Frictional force 
N
From the formula of frictional force,
Where 
coefficient of static friction, 
Put the above values and find the coefficient of static friction.
Therefore, the coefficient of static friction between your partner and the floor is 0.55
The work done is positive and is equal to 20000 J
<h3>What is work done?</h3>
Work done is defined as the product of force and the distance moved by the force.
Mathematically:
- Work done = force * distance
The work done by the force = 20 * 1000 = 20000J
The work done is positive and is equal to 20000 J

AnswerIt is continuously falling towards the surface of the earth
Explanation:
since gravity from earth is the thing that keeps it constantly in orbit
Answer:
A feature and a coin dropped from the same height falls at the same speed at the condition at free fall,both coin and feature gain same acceleration of 9.8m/s^2.
Answer:
Explanation:
compressibility = 1 / bulk modulus of elasticity ( B )
B = 1 / 4.8 x 10⁻⁵ = Δp / Δv /v ( Δp is change in pressure , Δv is change in volume )
1 / 4.8 x 10⁻⁵ = 429 / Δv /v
Δv /v = 429 x 4.8 x 10⁻⁵
= 2059.2 x 10⁻⁵
= .021
v = m / d ( d is density and m is mass of the water taken )
taking log and then differentiating
Δv /v = - Δd / d
- .021 = - Δd / d
Δd =.021 x d
= .021 x 998
= 20.9
new density
= 998 + 20.9
1018.9 kg/m3
