Answer:
Explanation:
a = 4ms⁻², Vf = 180 m/s & Vi = 140m/s
a = 
4 = 
t = 40/4
t = 10sec
To Measure Distance Use third Equation of Motion:
2aS = Vf²-Vi²
S = 
S = 12800/8 = 1600m
Answer:
When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions. The resulting compound is called an ionic compound.

Answer:
110 N
Explanation:
When a force is applied on a body and body does not move, it means the body remains at rest.
In this condition, there is a contact force between the body and the floor which is called static friction.
Th static friction force is a self adjusting force and comes into play when the body is at rest.
Here, the applied force is 110 N and the chest is not moving, that means a static friction force is acting between the chest and the floor. This static friction force is the force of contact between the chest and the floor. The static friction force is equal to the applied force when the body does not move.
So, the contact force between the chest and the floor is 100 N.
It's Z.
Without any force acting on it an object travels in a straight line.
In order to bend away from a straight line the object needs a force acting on it.
In order to move along a circle, the force on the object points toward the center of the circle. It's called the centripetal force.
Since the object's direction is changing it has acceleration.
The acceleration points toward the center of the circle.
