B. When the sun and the moon are aligned, their combined gravitational force attracts the water, causing super high tides on one side of the planet, and super low tides on the opposite side.
Answer:
Mary will have to wait for 63.2 seconds
Explanation:
Time required for the apple to drop from a height of 17.0 m above the ground to 1.65 m above the ground is given by the formula below:
t = √2h/g where h is height through which the object falls, g is acceleration due to gravity
h = 17.0 - 1.65 = 15.35 m
g = 9.8 m/s²
t = √(2 * 15.35/9.8)
t = 1.77 s or approximately 1.8 s
Time taken for bill to get to the point below Mary's window is given below;
time taken = distance/velocity
distance = 130 m; velocity = 2.0 m/s
time taken by Bill = 130/2.0 = 65 s
Therefore, Mary will have to wait for (65 - 1.8) s = 63.2 seconds
Weight Force of Junior = m g = 115kg x 9.81 m/s^2 = 1128.15N then
compute for the friction force
Friction Force= WF x (coefficient of kinetic friction) = 1128.15N x 0.35 = 394.8525N or 395N
But you can compute in a straightway:
Solution:
= 115 x 9.81 x 0.35
= 394.85
= 395 N
It will still give the same results.
Divide 360000 by 200 to get 1800 seconds, or half of hour.
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!
