As we know that work done by external environment is given as
here we know that
P = 200 N/m^2
now we will have
so work done by external atmosphere will be 40 J
so correct answer will be
A. 40 joules
Answer:
x=2.4t+4.9t^2
Explanation:
This equation is one of the kinematic equations to solve for distance. The original equation is as follows:
X=Xo+Vt+1/2at^2
We know that the ball starts at rest meaning that its initial velocity and position is zero.
X=0+Vt+1/2at^2
Since it is going down the ramp, you can use the acceleration of gravity constant. (9.81 m/s^2) and simplify that with the 1/2.
X=Vt+4.9t^2
Note: Since the positive direction in this problem is down, you are adding the 4.9t^2, but if a question says that the downward direction is negative, you would subtract those values.
Now, substitute in your velocity value.
X=2.4t+4.9t^2
Answer:
3 m/s
Explanation:
The computation of speed is shown below:-
We will compute the equation by using the law of conservation of momentum; also, the total momentum prior and following the collision must be conserved. Therefore we can write the equation is the following manner:-
where the symbols represent
150 kg is the mass of spaceship 1 = m1
150 kg is the mass of spaceship 2 = m2
0 m/s is the initial velocity of spaceship 1 = u1
6 m/s is the initial velocity of spaceship 2 = u2
and v is the velocity of the 2 ships so that they can collide and combined together
For v we will get the following equation to reach the speed
The average speed of an equatorial point is given by the ratio between the distance covered during one complete rotation (therefore, the circumference of Jupiter at the equator) and the time to complete one rotation:
where S is the circumference and t the time.
The radius of Jupiter is
so the circumference at the equator is:
While the time to complete one rotation is (in seconds)
Therefore the average speed of a point at the equator is
Answer:
Explanation:
answer: 4 velocity.
if nominal gdp is 1800 and the money supply is 450, then what is velocity?
