Answer:
273 Kelvin
Explanation:
If -273 Celsius is 0 Kelvin, then 273 Kelvin will be 0 Celsius.
Answer:
(A) 3.92 m/s²
Explanation:
From friction,
F = μR .................. Equation 1
Where F = Frictional force, μ = coefficient of static friction, R = Normal reaction.
But,
R = mg and
F = ma
therefore
ma = mgμ
Where a = acceleration, g = acceleration due to gravity, m = mass of the crate.
a = gμ...................... Equation 2
Given: μ = 0.4
Constant: g = 9.8 m/s
Substitute into equation 2
a = 0.4(9.8)
a = 3.92 m/s²
Hence the right option is (A) 3.92 m/s²
understandable terms created for the physichs terms can create mass destruction in the fires created with force
<span>Torque can be calculated by multiplying the force and the "perpendicular distance"
