Yes. It means that the acceleration increases at a constant rate, for example 3 mph every second.
Answer:
-5 cm
Explanation:
We can use the lens equation:
where
f = -7 cm is the focal lenght
p = 14 cm is the distance of the object from the lens
q is the distance of the image from the lens
Solving the equation for q, we find
Answer : 2446 years.
Explanation :
Length of semi major axis is,
According to Kepler's third law, square of time period of an orbit is directly proportional to the cube of the semi major axis.
i.e
where G is gravitational constant
M is mass of sun,
So,
since,
So, orbital period is approximately 2446 years.
I got 15.04 m/s. What I did was I made a little chart. Hopefully the picture helps
Explanation :
It is given that,
Side of square,
It is given that, the potential at point c is equal to zero.
So, potential at point a due to and is given as:
where,
So, (Since, is negative)
Hence, the potential at a due to and is equal to 0 V.
