What is the magnitude of the force of gravity acting on a box that has a mass of 100 kilograms and is at sea level
2 answers:
Answer:
Force of gravity, F = 980 N
Explanation:
Given that,
The mass of the box, m = 100 kilograms
We need to find the magnitude of the force of gravity acting on a box. It can be calculated using Newton's second law of motion which states the force is given by :
F = ma
a = acceleration
Here,
F = mg
g = acceleration due to gravity
F = 980 N
Hence, the force acting on the object is 980 N.

<em>Choice: c. 6sec</em>
Explanation:
<u>Horizontal Launch </u>
When an object is thrown horizontally with a speed (v) from a height (h), it describes a curved path ruled by gravity until it finally hits the ground.
The horizontal component of the velocity is always constant because no acceleration exists in that direction, thus:
The vertical component of the velocity changes in time because gravity makes the object fall at increasing speed given by:
Where
To calculate the time the object takes to hit the ground, we use the same formula as for free-fall, since the time does not depend on the initial speed:
The marble rolls the edge of the table at a height of h=180 m, thus:
t = 6 sec
Choice: c. 6sec
Five locations are marked on the world map. The spot that is prone to hurricane mostly A.
<h3>What is hurricane?</h3>A hurricane is a cyclone with winds of 74 miles (119 kilometers) each hour or more prominent that is typically joined by downpour, thunder, and lightning, and that occasionally moves into calm scopes.
The locations on the world map spot A, B, C, D, E are regions with country prone to hurricane.
The SPOT A, is GULF of Mexico, a sea bowl nearer to the Atlantic sea, encompassed with the North American landmass, the Hawaiian island is likewise inside that locale.
The SPOT B, is the southern Pacific sea with nations like BRAZIL, PERU, ECUADOR, CHILE, in that equivalent locale. This is likewise visited by the tropical storm.
The SPOT C, is inside the locales of AFRICA, nations at the edge are likewise impacted by typhoon.
The SPOT D, is Asian landmass with Russia at the edge. They are likewise inclined to typhoon.
The SPOT E, is the North Pacific sea locale situated at the upper left hand side of the world guide, with nations like Canada, Alaska and co. Near the artic circle.
Thus, location A is the most prone to hurricanes.

Answer:
150 inches (12.5 ft)
Explanation:
The work done to lift the 500 pound block 3 inches should be the same as that to lift the 10 pond object a given distance.
The following is the equation one needs to solve:
therefore solving for the distance "x" gives as the answer (in inches):
which can also be given in feet as: 12.5 ft
