0.2 atm.
by boyles law, PV= constant. hence, p1*v1=p2*v2
so, 400*1=p2*2000 (careful with units, 1litre= 1000 ml)
so, you get p2=0.2 atm
A body of mass m has weight
F = GMm/r²
on the surface of the Earth, where G is the universal gravitational constant, M is the mass of the Earth, and r is it's radius.
If the weight is to be halved, then we have
1/2 F = 1/2 GMm/r² = (1/√2)² GMm/r² = GMm/(√2 r²)
so the distance between the body and the planet's center needs to be
√2 × 6.4 × 10⁶ m ≈ 9.1 × 10⁶ m
Answer:
Explanation:
The formula for the double-slit interference pattern is:
where:
m is the order of the maximum
is the wavelength
D is the distance between the slits and the screen
d is the distance between the two slits
If we assume for instance m=5, the formula gives us the distance between the fifth maximum and the first maximum. However, this will also gives us the distance between the fifth minimum and the first minimum, as the minima fall exactly between two maxima.
Therefore, if we use:
We can find the wavelength of the light:
Answer:
Mass, m = 1561.23kg
Explanation:
Given the following data;
Weight = 15300N
We know that acceleration due to gravity is equal to 9.8m/s²
To find mass;
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
Where;
- m represents the mass of an object measured in kilograms.
- g is the acceleration due to gravity measured in meters per seconds square.
Substituting into the equation, we have;
<em>Mass, m = 1561.23 Kg</em>
<em>Therefore, the mass of the car is 1561.23 kilograms.</em>
This assumes that the wave has velocity c (is light).
