Answer:
The uncertainty in the volume of the sphere is
Solution:
As per the question:
Measured radius of the sphere, R = 135.4 m
Uncertainty in the radius,
We know the volume of the sphere is:
We know that the fractional error for the given sphere is given by:
where
= uncertainty in volume of sphere
Now,
Now, substituting the suitable values:
Answer:
Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. ... Their movement generates an electric current and causes each electron to act like a microscopic magnet.
Explanation:
Answer:90.3 kg
Explanation:
Given
Mass of astronaut
Initial velocity of canister
Final velocity of canister
Final speed of Astronaut
let M be the mass of canister
As there is no external force therefore we can conserve momentum
Answer:
Net acceleration = 3.5m/s²
Explanation:
Given the following data;
Mass, m = 40kg
Normal force, Fn = 400N
Applied force, Fapp = 195N
Force of friction, Ff = 55N
Mathematically, the net force is given by the formula;
Substituting into the equation, we have;
<em>To find the acceleration;</em>
Making acceleration "a" the subject of formula;
Net acceleration, a = 3.5m/s²
