Answer:
The first option, "The more mass an object has, the greater the gravitational pull.
"
Explanation:
Newton's Law of Gravity states that 
, where G is the gravitational constant, 
and 
are the masses of the two objects, and <em>r</em> is the distance between the objects' centers. Because the objects' masses are in the fraction's numerator, they are directly proportional to 
, and increasing the mass of one or both objects increases the gravitational pull.
Please have a great day! I hope this helps you understand the question!
Answer:
The length is 
and the angle is 
Explanation:
The period 
of the pendulum is related to its length 
by
where 
is the acceleration due to gravity.
Solving for we get
putting in 
and we get:
There are two forces acting on the pendulum: The gravitational force 
and the 
student's force. Therefore, the angular displacement 
that these forces give is
putting in 
, 
, and we get
Answer:
8.64 m/s
Explanation:
v1 = 8 m/s, v2 = ?, P2 - P1 = 5338 Pa, density of water, d = 1000 kg/m^3
By the use of Bernoulli's theorem
P 1 + 1/2 x d x v1^2 = P2 + 1/2 x d x v2^2
P2 - P1 = 1/2 x d x (v2^2 - v1^2)
5338 = 0.5 x 1000 x (v2^2 - 64)
10.676 = v2^2 - 64
v2^2 = 74.676
v2 = 8.64 m/s
Answer:Principle of rectilinear propagation of light
Explanation:Principle of rectilinear propagation of light
Rectilinear propagation of light refers to the propensity of light to travel along a straight line without any interference in its trajectory. ... It is because light travels along a straight line and leaves only the areas where the object interferes.
