Answer: mass = 48.47 kg.
Explanation:
Formula : Weight = mg , where m = mass of body , g= acceleration due to gravity .
Given: Weight = 475 N
Substitute all values in formula , we get
Hence, his mass = 48.47 kg.
Answer:
transfer of electric charge by rubbing conduction. mark me as brainest
In order to increase the gravitational forces between two objects,
you have exactly two choices:
-- Increase the product of the two masses.
-- Decrease the distance between their centers of mass.
The correct option is D.
Sound proofing is usually achieved by using materials that absorbed or reduce sounds. Different materials are used in sounding proofing and these differ in their abilities to absorb or reduce sounds. The coefficient of absorption of a material refers to that material ability to absorb sound. The higher the percentage of a material absorption coefficient, the better the material's ability to absorb sound. Thus, in the question given above, the material with 62% absorption coefficient have the greatest ability of the three materials to absorb sound effectively. <span />
Answer: M = 1797.75 kg
Explanation:
given parameters are;
speed V = 26.7 M/S.
momentum P = 4.8×10^4 KGM/S.
What was the mass of the V. A-3?
Momentum P is the product of mass and velocity. That is, P = MV
Substitute V and P into the formula
4.8×10^4 = 26.7 × M
Make M the subject of formula
M = 4.8×10^4/ 26.7
M = 1797.75 kg
Therefore, the mass of the V. A-3 was 1797.75 kg
