2.) Jeremy is pushing his two children on a set of swings. He gives his daughter a push and she swings about three feet high. Jeremy gives his son the same push, but he only swings about two feet high. What could account for the difference in how high the kids got?

Jeremy's daughter has more mass, so it takes less force to get her into the air.
Jeremy's son has more mass, so it would take more force to reach the same height as his daughter.
Jeremy's son has less mass, so it would take more force to reach the same height as his daughter.
Jeremy's daughter has more mass, so she accelerates faster than his son.

Answer:

About 66 miles per hour

Explanation:

Based on the information given we can assume the car traveled the same number of miles every hour meaning all we need to do is divide.

400/6 ≈ 66 miles per hour

Answer

66 mph

Explanation:

400 ÷ 6 = 66.666666666666666.......

Answer:

415.8N

Explanation:

Given:

weight of a luggage = 69.3 N

But

✓(weight on the Earth) is equivalent to 6 times weight if the moon.

✓Then, weight on the Earth) =( 69.3N × 6)

✓weight on the Earth) = 415.8N

force of a tennis ball

for a top player,a tennis ball may leave the racket on the with a speed of 55m/s(about 120mi/h).if the ball has a mass of 0.060kg and is in contact with the racket for about 4ms(4×10)s.estimate the average force on the ball

Answer:

B. Acceleration in the direction of motion speeds you up

Explanation:

Acceleration is defined as when something gains speed. For example, when a car speeds up. Deceleration is when the car slows down, and looses speed. When defining these terms, think of a car going faster, then slowing down at a red light.

The number of waves produced by the musical instrument during the given time is 148 waves.

Frequency of a wave is defined as the number of oscillations completed by the wave in one second.

Here,

The frequency of the wave, f = 370 Hz

That means the wave completes 370 oscillations in 1 second. Or 370 waves are produced by the musical instrument in 1 second.

The time taken by the instrument to produce waves, t = 0.4 s

Therefore,

The number of waves produced by the musical instrument during this time is,

n = f x t

n = 370 x 0.4

n = 148

Hence,

The number of waves produced by the musical instrument during the given time is 148 waves.

Answer:

The 5 Forces

Explanation:

The five forces that influence wind speed and direction are: Pressure gradient force (flow from high to low pressure) Coriolis force (apparent deflecting force due to the rotation of the Earth) Turbulent drag (Earth's surface or objects like trees or grass resist air flow and decrease wind speed near the ground)

Answer:

Q1: c

Q2: a

Explanation:

you can tell the factors by looking at the formulas for kinetic and potential energy

for question 1  look at the formula for kinetic energy

[tex]KE=\frac{1}{2} mv^{2}[/tex]

the variables needed in order to calculate an object's kinetic energy are mass and velocity.

hence, when mass and velocity changes, kinetic energy changes, showing that mass and velocity are the factors affecting kinetic energy

same thing for the second question

[tex]PE = mgh[/tex]

as g (acceleration due to gravity) is considered constant (10 [tex]m/s^{2}[/tex] ) it will not be considered as a factor

and thus, the factors affecting potential energy are mass and height

Answer:

A neutron star is the most intensely dense object in all the universe. Of course, the argument can be made that a black hole is the most dense, but considering that a black hole is technically beyond the event horizon, it is neutron stars that get the top spot for the being the ‘most dense’.

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82
