Answer:
b option mass will not change based on location while weight will changr based on gravitational pull
bcz in the formula of weight w=mg
so w is directly proportional to g
Answer:
The intensity is
Explanation:
From the question we are told
The frequency of the electromagnetic wave is
The peak value of the electric field is
Generally the intensity of this wave is mathematically represented as
Where c is the speed of light with value
is the permittivity of free space with value
Substituting values into equation for intensity
Converting to we divide by 10,000
Answer:
A
I say this because exponential growth takes place when a population per Capita growth stays the same
Answer:
The required amplitud is 0.11cm
Explanation:
To solve this problem it is necessary to apply the concepts related to simple harmonic motion, where displacement is given by
Where,
A = Amplitude
f = Frequency
t = time
If we derivate the expression we can obtain the Acceleration, there
x would be A for the minimum amplite of vibration, then
Replacing with out values,
Therefore the required amplitud is 0.1146cm
The acceleration of the leaf as it falls is zero.
Explanation:
There are to forces acting on the leaf;
(a) force of gravity acting downwards
(b)Air resistance acting upwards
At some point force of gravity acting downwards balances the force of air resistance acting upwards and thus the net force on the leaf is zero.As the net force on the leaf is zero, the acceleration of the leaf =0.
Because of this zero net force, the leaf will acquire a constant velocity after some time called as terminal velocity and will continue to move with this constant velocity.
