Do the data support or refute the hypothesis, normally, the data for the first part of the experiment support the first hypothesis.
<h3>What is a hypothesis test?</h3>
Hypothesis testing refers to the formal procedures used by statisticians to accept or reject these hypotheses. When trying to make decisions, it is convenient to formulate assumptions or conjectures about the populations of interest, which consist of considerations about their parameters.
As a result of this, we can see that from the complete text, there is a set of data which is used to show the force that is applied to a cart that causes the acceleration of the cart to increase which supports Newton's second law.

Answer:
w2=5.1736x10^-6m
Explanation:
The relation between the wavelength and width is:
sin(Ф)=m*λ/w
Since the mass and the angle is the same in both cases so:
sin(Ф)=m*λ1/w1
sin(Ф)=m*λ2/w2
The mass and the sinФ are factor in both elements so:
λ2/w2=λ1/w1
w2=w1*λ2/λ1
w2=4.1x10^-6m*665x10^-9m/527x10^-9m
w2=5.1736x10^-6m
Answer:
Its final velocity and how much time it takes to reach the water
Explanation:
The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:
where
v is the final velocity
u = 0 is the initial velocity
is the acceleration of gravity
s = 52 m is the distance covered during the fall
Solving for v,
We can also find how much time it takes to reach the water, using the equation
where
v = 31.9 m/s is the final velocity
u = 0 is the initial velocity
t is the time
And solving for t,
Answer:
18 m
Explanation:
G = Gravitational constant
m = Mass of planet =
= Density of planet
V = Volume of planet assuming it is a sphere =
r = Radius of planet
Acceleration due to gravity on a planet is given by
So,
Density of other planet =
Radius of other planet =
Since the person is jumping up the acceleration due to gravity will be negative.
From kinematic equations we have
On the other planet
The man can jump a height of 18 m on the other planet.
The answer is to orient themselves and find food.
