Explanation:
We know that that the range of the ball on the earth
therefore, range of the ball on moon
therefore,
Therefore, the range of ball will be 6 times on the moon than that on earth
The cathode ray experiment showed that they were both negative and positive charges in the atom. This led him to theorize that the charges MUST be spread out evenly throughout the atom. this is the plum-pudding model
Answer:
The answer to your question is
a) t = 2.55 s
b) t = 5.5 s
Explanation:
Data
vo = 25 m/s
h = 2 m
g = 9.81 m/s
Formula
t = -(vo)/g
a)
t = -(25)/9.81
t = 2.55 s
b)
Tt = 2t
Tt = 2(2.55)
Tt = 5.1 s
Time in the last 10 m
10 = 25t + (1/2)(9.81)t²
Simplify
10 = 25t 4.91t²
4.9t² + 25t - 10 = 0
Solve the equation using an online calculator
t₁ = 0.37 s t₂ = -5.47 s
The correct answer is t₁, t₂ is incorrect because there are no negative answers.
Total time = 5.1 + 0.37
= 5.5 s
To firstly answer this question, you must know what the Coriolis effect is. In simple terms, it can be defined as something that causes displacement - making things move at a curve, rather than a straight line. This aforementioned effect applies to winds within the hemispheres. Here's how this effect messes with the winds.
Winds move in a counterclockwise direction in the Northern Hemisphere and in a clockwise direction in the S. Hemisphere.
For this case, the first thing we are going to do is define a reference system.
We define the vertical axis of the reference system, pointing upwards.
Therefore, doing summation of forces in vertical direction we have:
Then, since we want the net force to be equal to zero, then:
From here, we clear the force that we must apply on the object:
The positive sign means that the force points upwards.
Answer:
to create a net force of zero on the object you must apply:
33 Newton upwards.
