Acceleration' is any change in the speed or direction of motion. we can look through the choices:
A). /
B). No. Neither speed nor direction changed.
C). /
D). Yes. The boy's direction changed.
Answer:
Dx = - 74.82 [m]
Explanation:
In order to solve this problem we must decompose the horizontal and vertical axes using the trigonometric functions of the sine and cosine.
For the x component, we must use the cosine of the angle.
Dx = 101*cos(42.2) = 74.82 [m]
Now we must appreciate that the x component is going to the left therefore we have a negative component in the x-direction.
Dx = - 74.82 [m]
Answer:
B. It has mass
Explanation:
The Newtons Universal gravitacion law is : F = G.
, where <u>F</u> is the force exerted , <u>m1</u> and <u>m2</u> are the earth's mass and the object's mass, <u>d</u> is the distance and <u>G</u> the gravitacional constant. Comparing to the options we can say that the Earth exerts a gravitational force on objects on its surface because of its mass.
If the mass of the sun is 1x, at least one planet will fall into the habitable zone. if I place a planet in orbits 1, 3, 5 , 6 and all planets will orbit the sun successfully.
<h3>
What are planets?</h3>
Planets are the large spherical shaped objects that rotate about the Sun in the elliptical orbits.
Planets are shaped from Planetary cloud. The dust storm and gases gathers under its own weight. The dense matter beginnings pivoting at high paces and accumulates more mass. The center structures, the star and rest of it ultimately levels into a curved plate from which planet is formed.
Thus, if I place a planet in orbits 1, 3, 5 , 6 and all planets will orbit the sun successfully.

Answer: The reason for the differences in density is the composition of rock in the plates. When two plates come in contact with each other through plate tectonics, scientists can use the density of the plates to predict what will happen. Whichever plate is more dense will sink, and the less dense plate will float over it.
