a.
Volume,
Length of water column in the right arm=
b.
In equilibrium condition
Pressure at point A=Pressure at point B
Answer:
The acceleration is given by de second derivative of x(t) which is equal to m/s^2
Explanation:
a) We have the equation x(t)=at^4+bt^3+ct which is the position of the body of mass m at a time t
Where a, b and c are constants
From the rules of differenciation we have that the first derivative of the position is the velocity and the second derivative is the acceleration.
Hence the first derivative of the function is equal to [/tex] m/s
Don´t forget to write down the unities
Then we have to derivate again this equation, so we have
m/s^2[/tex]
b) Remembering the Newton´s laws we know that
where:
F is the force
m is the mass
and a is the acceleration
From the first part we know the value of the acceleration which is
m/s^2
So using the second law formula and replacing the values we have that
F=m( ) N
Remember the that N= Newton which is kg*m/s^2
Answer:
The acceleration of the skateboarder is 2.067 m/s²
Explanation:
Given;
initial velocity of the skateboarder, u = 0.8 m/s
final velocity of the skateboarder, v = 7 m/s
time of motion, t = 3 s
The acceleration of the skateboarder is given as;
Therefore, the acceleration of the skateboarder is 2.067 m/s²
The force of the ball on the club is 200 N backward.
Option 2 is the correct answer.
<h3>
Newton's Third Law </h3>
Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
Given that the force of a golf club on a golf ball is 200 N forward direction.
In this situation, newton's third law of motion is applicable on the ball.
According to newton's third law, the magnitude of the force will be the same. Hence,
Force = 200 N
The direction of the force will be opposite. If the force on a golf ball is applied in forward direction, then the force on the golf club will be applied in the backward direction.
Hence we can conclude that the force of the golf ball on the golf club will be 200 N in the backward direction.

Here is your answer
C. towards the floor
REASON:
Using Fleming's Left hand rule we can determine the direction of force applied on a moving charged particle placed in a magnetic field.
The direction of current will be just opposite to the direction of electron(negative charge) because current moves from positive to negative terminal whereas electron moves from negative to positive terminal.
So, direction of current- North to South
Now applying Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.
