It is 10.20 m from the ground.
<u>Explanation:</u>
<u>Given:</u>
m = 0.5 kg
PE = 50 J
We know that the Potential energy is calculated by the formula:

where m is the is mass in kg; g is acceleration due to gravity which is 9.8 m/s and h is height in meters.
PE is the Potential Energy.
Potential Energy is the amount of energy stored when an object is stationary.
Here, if we substitute the values in the formula, we get

50 = 0.5 × 9.8 × h
50 = 4.9 × h

h = 10.20 m
Density is mass divides by volume, so
89.6g / 10cm^3 =8.96g /cm^3
*cm^3 is a standard unit of volume*
Answer:
Stationary front
Explanation:
A stationary front is usually defined as a front when both the warm as well as cold front does not move and remain stationary. It is because the force exerted by both the air masses against each other is not so high to displace one another. In this case, the wind blows parallel instead of blowing perpendicular to the front.
Generally, in weather maps, the stationary front is shown by the alternate use of blue triangles and red semi-circles, where the triangle faces the warm front and the semi-circle faces the cold front.
Answer:
In mine I said to build the boat accordingly based on what is going to be in it
Explanation:
just remember the density of the boat cannot change but the volume and the mass can
Answer: Northwest.
Explanation:
After the collision the second object which was at rest would change its direction and move towards the Northwest. The object in motion was coming from the east and traveling towards the west, where it deflects against a stationery object which changes its direction to southeast. And the object which was at rest moves toward the northwest.
