Answer:
C) It increases to 2.0 cm
Explanation:
In a double-slit diffraction experiment, the distance on the screen between two adjacent maxima is given by
where
is the wavelength of the wave
D is the distance of the screen from the slits
d is the separation between the slits
In this problem, the initial distance between adjacent maxima is 1.0 cm. Later, the slit separation is cut in a half, which means that the new slit separation is
Substituting into the equation, we find that the new separation between the maxima is
So, the distance increases by a factor 2: therefore, the new separation between the maxima will be 2.0 cm.
That depends on WHERE the rig is, because
weight = (mass) x (acceleration of gravity where the object is) .
-- If the truck is on Mars, then
Weight = (36,000 kg) x (3.71² m/s²) = 133,560N.
-- If the truck is on the moon, then
Weight = (36,000 kg) x (1.62 m/s²) = 58,320N.
-- If the truck is on Earth, then
Weight = (36,000 kg) x (9.81 m/s²) = 353,160N.
It all depends.
Potential energy due to gravity= mass x gravity x height
The correct answer to the question is by increasing their masses, or by decreasing the separation distance between them.
EXPLANATION:
Let us consider two bodies having masses M and M' respectively . The two bodies are separated from their centre of masses by a distance of R.
As per Newton's law of gravitation, the two bodies will exert gravitational force on one another. The gravitational force produced between them is calculated as -
Gravitational force
Here, G is the gravitational force constant.
From above, we see that the gravitational force is directly proportional to the product of masses of two bodies and inversely proportional to the square of separation distance between them.
Hence, the gravitational force between two objects can be increased by increasing their masses, or by decreasing the distance between them.
