Answer:
Because they have already made an impact within our atmosphere
Answer:
energy = 391.902 kJ /mol
Explanation:
given data
wavelength = 305 nm = 305 ×
m
to find out
average energy
solution
we know speed of light is 3 ×
m/s
so we find frequency here first by speed of light formyla
speed = wavelength × frequency
3 ×
= 305 ×
× frequency
frequency = 9.8360 ×
so energy is
energy = hf
here h = 6.62 ×
J-s
so
energy = 6.62 ×
× 9.8360 ×
energy = 6.51 ×
J
so
energy = 6.51 ×
×
kJ/mol
energy = 391.902 kJ /mol
Answer:
Pressure on both feet will be
Explanation:
Weight of the person F = 500 N
Area of foot print 
Area of both the foot 
We have to find pressure on both the feet
Pressure is equal to ratio of force and area
So pressure 

So the pressure on both feet will be
when person stands on both feet.
Answer:
Yes, Centripetal Force acts on the Car.
Explanation:
When a car undergoes a circular motion, a centripetal force acts onto it.
Centripetal Force = [m*(v^2)]/R , where
- R is the radius of curve
- v is the constant speed
- m is the mass of the car
Answer:
Similarity: >>Time is independent variable and such is on the x-axis. ... >>Distance time graph tells you how much distance you have travelled, while velocity time graph tells you your acceleration. The difference between them is that the velocity-time graph reveals the speed of an object (and whether it is slowing down or speeding up), while the position-time graph describes the motion of an object over a period of time.
