With a diameter that's 11 times larger than Earth's, Jupiter is the largest planet
Answer:
1.06 secs
Explanation:
Initial speed of sled, u = 8.4 m/s
Final speed of sled, v = 5.8 m/s
Coefficient of kinetic friction, μ = 0.25
Using the impulse momentum theory, we know that the impulse applied to the sled is equal to change in momentum of the sled:
FΔt = mv - mu
where m = mass of the object
Δt = time interval
F = force applied
The force applied on the sled is the frictional force, which is given as:
F = -μmg
where g = acceleration due to gravity
Therefore:
-μmgΔt = mv - mu
-μmgΔt = m(v - u)
-μgΔt = v - u
Making Δt subject of formula:
Δt = (v - u) / -μg
Δt = (5.8 - 8.4) / (-0.25 * 9.8)
Δt = -2.6/ -2.45
Δt = 1.06 secs
It took the sled 1.06 secs to travel from A to B.
I believe the answer is c
The correct answer is:
<span>B) orange, yellow, green, blue
the energy of the photons of light is directly proportional to the frequency of the light. This means that the lower the frequency, the lower the energy, and the higher the frequency, the greater the energy.
Therefore, the order in increasing energy is exactly the same as the order in increasing frequency, which is:

Answer:
Explanation:
Our values are,
We have all the values to apply the law of linear momentum, however, it is necessary to define the two lines in which the study will be carried out. Being an intersection the vehicle of mass m_1 approaches through the X axis, while the vehicle of mass m_2 approaches by the y axis. In the collision equation on the X axis, we despise the velocity of object 2, since it does not come in this direction.
For the particular case on the Y axis, we do the same with the speed of object 1.
By taking a final velocity as a component, we can obtain the angle between the two by relating the equations through the tangent
Replacing in any of the two functions, given above, we will find the final speed after the collision,
