Answer:
D: Left, Down
Explanation:
Assuming that the bullet has already left the gun, there are only two forces acting on the bullet now, during its motion:
- The force of gravity (the weight of the object), acting downward
- The air resistance acting against the direction of motion (so, if the bullet is moving right, the air resistance acts to the left)
As a result of these two forces:
- The bullet will accelerates downward in the vertical direction, due to the force of gravity
- The bullet will decelerated (slow down) along the horizontal direction, due to the air resistance that acts against the direction of motion of the bullet
So, the bullet will acquire a parabolic path.
Therefore, the correct answer is
D: Left, Down
The answer is
-Small f and large D.
The explanation:
-when The car jack is an example of a machine, which is defined as anything that a person can use to make the exertion of force easier.
-So with the small force he exerts on the jack, the distance that the car is lifted up increases
.
and People needs help of machines to increase their force. People cannot lift a car without a machine. Using the leverage or hydraulic principles the machines increase your force.
If you use a large leverage you execute a large movement with little force and as result the other side will move small distances with a greater force.
Answer:
If both parents had a recessive allele for blue eyes and they had a brown phenotype it is completely possible for the child to have blue eyes.
Explanation:
Chromosomes play the role of transfering the encoded strands of DNA to the child. Genotypes are the traits or groups of traits transferred and need to carry the trait of blue eyes in order for the child to have them. As long as the parents had a recessive allele for blue eyes they could have a blue eyed child.

Answer:
The force acting on the ball is 92.4 N.
Explanation:
Given that,
Initial speed of the ball, u = 0
Final speed of the ball, v = 31.6 m/s
The average power generated during the serve is 2920 W. Power generated by an object is given by :
W is the work done, W = Fd
Since, 
So,
F is the force acting on the ball
So, the force acting on the ball is 92.4 N. Hence, this is the required solution.
