Answer:
minimum distance will be 13.33 m
Explanation:
We have given the speed of both the car = 80 km/h
We know that 1 km =1000 m
And 1 hour = 60×60 =3600 sec
So
Reaction time is given as t = 0.60 sec
Minimum distance will be equal to the distance driver needed during reaction time
So minimum distance = u ×t =22.22 ×0.60=13.33 m
The answer to this question would be Refract.......
Answer:
5.71 N/m
Explanation:
From the question given above, the following data were obtained:
Extention (e) = 3.5 m
Force (F) = 20 N
Spring constant (K) =?
From Hooke's law,
F = Ke
Where :
F => is the force applied
e => is the extention caused by the force
K => is the spring constant
With the above formula, we can obtain the spring constant of the spring as follow:
Extention (e) = 3.5 m
Force (F) = 20 N
Spring constant (K) =?
F = Ke
20 = K × 3.5
Divide both side by 3.5
K = 20 / 3.5
K = 5.71 N/m
Thus, the spring constant of the spring is 5.71 N/m
At atmospheric pressure, a gas will have a certain density at that pressure. Density is measured a mass divided by the volume. If you increase the pressure in a cylinder of constant mass of gas particles, you decrease the volume at which gases occupy thus from the equation density is equal to mass over volume, a volume decrease with a constant mass yields a higher density. Therefore increasing the pressure increases the density.
Answer:
The diameter of mirror
Explanation:
Given that,
Wavelength = 2 μm
Resolution = 0.1
We need to calculate the diameter of mirror
Using formula of resolution
Put the value into the formula
Hence, The diameter of mirror
