Larry weighs 300 N at the surface of Earth. What is the weight of Earth in the gravitational field of Larry
1 answer:
The gravitational force of attraction between two objects is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.
Where,
G = Gravitational Universal Constant
M = Mass of the Planet
m = Mass of the object
r = Distance
Therefore the amount of force exerted by the first object on the second object is equal to the amount of the force exerted on the second object by the first.
The gravitational force exerted by Larry on the Earth is same as the force exerted on Larry by the Earth.
That is 300N.

Answer:
P-value of the test statistic is 2.499
Explanation:
given data:
size sample is 24
sample mean is 414 gm
standard deviation is 15
Null hypotheis is
level of significance is 0.01
from test statics
degree od freedom is = n -1
df = 24 -1 = 13
t = -1.959
from t table critical value of t at 0.1 significane level and 23 degree of freedom is 2.499
