Answer:
7.5 x 10⁻⁸N
Explanation:
Given parameters:
Mass 1 = 60kg
Mass 2 = 75kg
Distance between the bodies = 2m
Unknown:
Gravitational fore = ?
Solution:
The gravitational force between the two bodies can be derived using;
F =
G is the universal gravitation constant = 6.67 x 10⁻¹¹m³kg⁻¹s⁻²
Insert the parameters and solve;
F = = 7.5 x 10⁻⁸N
Answer:
641 nm.
Explanation:
Given that,
A transmission grating has 5200 slits/cm.
We need to find the longest wavelength that can be observed in the third order. Using grating equation as follows :
...(1)
d is slit spacing
No fo slit per unit length :
We know that, N = 1/d
For longest wavelength, θ = 90°
From equation (1)
Hence, the longest wavelength in third order for a transmission grating is 641 nm.
The net force acting on the two (2) kids is equal to 180 Newton.
<u>Given the following data:</u>
To determine the net force acting on the two (2) kids:
First of all, we would calculate the total mass of the two (2) kids:
Total mass = 90 kg.
<h3>How to calculate net force.</h3>In this exercise, you're required to calculate the magnitude of the net force that is acting on these two (2) kids running down the hall. Thus, we would apply Newton's Second Law of Motion.
Mathematically, Newton's Second Law of Motion is given by this formula;
Substituting the given parameters into the formula, we have;
Net force = 180 Newton.
