Answer:
BR
Explanation:
BR is good conducter of electricity
Answer:
So an object with mass is attracted to another object with mass, and the gravitational force is directly proportional to the masses of the two objects, and inversely proportional to the <em>square</em> of the distance between the two objects.
If distance were to increase, than the gravitational force would decrease. If mass were to increase, so would the gravitational force.
Explanation:
The label means that the bulb will consume 75 joules of electrical energy in 1 sec
Answer:
Plane spacing, 
Explanation:
It is given that,
Wavelength of x-ray, 
Angle the x-ray made with a set of planes in a crystal causing first order constructive interference is 30 degrees
We need to find the plane spacing. It is based on Bragg's law such that,
d is plane spacing
n = 1 here
So, the plane spacing is 
.
