Let us first know the given: Tennis ball has a mass of 0.003 kg, Soccer ball has a mass of 0.43 kg. Having the same velocity at 16 m/s. First the equation for momentum is P=MV P=Momentum M=Mass V=Velocity. Now let us have the solution for the momentum of tennis ball. Pt=0.003 x 16 m/s= ( kg-m/s ) I use the subscript "t" for tennis. Momentum of Soccer ball Ps= 0.43 x 13m/s = ( km-m/s). If we going to compare the momentum of both balls, the heavier object will surely have a greater momentum because it has a larger mass, unless otherwise the tennis ball with a lesser mass will have a greater velocity to be equal or greater than the momentum of a soccer ball.
Answer:
The time constant and its uncertainty is t ± Δt = 0.526 ± 0.057 s
Explanation:
If we make a comparison we have to:
y = A*(1-e^-(C*x)) + B
If the time remains constant we have to:
t = R*C = 1/C
In this way we calculate the time constant and its uncertainty. this will be equal to:
t ± Δt = (1/1.901) ± (0.2051/1.901)*(1/1.901) = 0.526 ± 0.057 s
Answer:
C
Explanation:
From above question we know that
A = 6.2 m
f = 1.6 rad/s
t = 3.5 s
x =?
We know that,
x = Acos(2pie ft)
Putting all values in above eq.
x = 6.2 x cos(2x3.142x1.6x3.5)
x = - 4.8
Displacement can never be negative so ignore - sign.
You need to form a hypothesis based on what is already known about gold and then devise an experiment to test this hypothesis.
For example, the density of gold is well known. So your hypothesis would be that if the rock were gold, you could predict the amount of water displacement in a beaker simply by measuring the weight of the rock.
The steps would be:
1. research what is already known about your field of investigation (in this case <em>gold</em>).
2. Using that information, formulate a hypothesis that allows you to make predictions.
3. Devise an experiment that can test your predictions.
