Answer:
9375 N
Explanation:
From the question,
Centripetal force (F) = mv²/r.................. Equation 1
Where m = mass of the car, v = velocity of the car, r = radius of the curve.
Given: m = 900 kg, r = 600 m, v = 25 m/s
Substitute these values into equation 1
F = (900×25²)/600
F = 9375 N.
Hence the centripetal force on the car is 9375 N
Answer:
SI unit of k (spring constant) = N/m
Explanation:
We have expression for force in a spring extended by x m given by
F = kx
Where k is the spring constant value.
Taking units on both sides
Unit of F = Unit of k x Unit of x
N = Unit of k x m
Unit of k = N/m
SI unit of k (spring constant) = N/m
Answer:1.55 times
Explanation:
Given
First wavelength
Second wavelength
According wien's diplacement law
where 
T=Temperature
Let 
be the temperatures corresponding to 
respectively.
Thus object with 
is 1.55 times hotter than object with wavelength
