A stuntman drives a car off of a parking garage. The car lands 68.38 meters away from the base of the garage. If the stuntman drove the car at 19 m/s, how tall is the parking garage?
Answers
Answer: 63.43 m
Explanation:
Given
Car lands 68.38 m away from the base of the garage
Stuntman drove the car with speed [tex]u=19\ m/s[/tex]
Since there is no acceleration in the horizontal direction, so there is no change in velocity
[tex]\Rightarrow 68.38=19\times t\\\Rightarrow t=3.598\ s[/tex]
time taken to cover 68.38 m is 3.598 s
In this time car travels a vertical distance of h
Such that we can write
[tex]\Rightarrow h=u_vt+\frac{1}{2}at^2\\\\\Rightarrow h=\frac{1}{2}gt^2\\\\\Rightarrow h=0.5\times 9.8\times (3.598)^2=63.43\ m[/tex]

How are infrared waves and radio waves similar? How might you use each?
Answers
Answer:
They are both eletro-magnetic waves, they are both outside of the range humans can see with our eyes. Infrared waves can can carry enough energy to give heat to objects. There is a lot of Infrared light that is put out by a fire and we feel that as the heat. Radio waves can be used to carry other signals like when we listen to the radio.
Explanation:
Answer:
Both infrared and radio waves are longer than visible light and are not considered harmful to humans.Infrared light is how remote controls communicate with electronics like televisions and stereos, while radio waves are how cell phone signals are transmitted.

O A. Reactions are faster when there is a lower concentration of
reactants.
Answers
Answer: The answer is C.
Explanation:Just took the quiz
The statement about the relationship between rates of reaction and concentration of reactants true is reactions are slower when there is lower concentration of reactants.
What is chemical reaction?The chemical reaction is the reaction between two reactants which led to the formation of products.
The products are substances which forms after reaction. The reactants are the substances which are original materials.
Oxygen is needed for the reactions that cause artifacts to decay in the ocean.
Some ancient shipwrecks have been well-preserved deep in the ocean.
Reviewing the information in the data table, we conclude that reactions are slower when there is lower concentration of reactants.
Thus, the correct option is C.

A pendulum has a mass of 0.060 kg swinging at a small angle from a light string, with a period of 1.4 s. What is the length of the pendulum?
Answers
Answer:
0.5 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 0.060 kg
Period (T) = 1.4 s
Lenght (L) =?
NOTE:
1. Acceleration due to gravity (g) = 10 m/s²
2. Pi (π) = 3.14
The length of the pendulum can be obtained as follow:
T = 2π√(L/g)
1.4 = 2 × 3.14 × √(L/10)
1.4 = 6.28 × √(L/10)
Divide both side by 6.28
1.4 / 6.28 = √(L/10)
Take the square of both side
(1.4 / 6.28)² = L/10
Cross multiply
L = 10 × (1.4 / 6.28)²
L = 0.5 m
Therefore, the length of the pendulum is 0.5 m
Answer:0.49

Ball A is projected vertically upwards at a velocity of 16m.s-¹ fron the ground. ignore the effects of air friction. use the ground as zero reference. a) calculate the time taken by ball A to return to the ground. b) draw a velocity time graph for ball A
Answers
Answer: 3.26 s
Explanation:
Given
The ball is projected upward with a velocity [tex]u=16\ m/s[/tex]
Using the equation of motion
[tex]s=ut+\frac{1}{2}at^2[/tex]
Here, displacement is zero as the ball returns to its initial position
[tex]\Rightarrow 0=16\times t-0.5\times g\times t^2\\\Rightarrow t(16-0.5\times 9.8\times t)=0\\\text{i.e.}\ t=\dfrac{16}{4.9}=3.26\ s[/tex]
the velocity of the ball at any instant is given by
[tex]v=u+at\\v=16-9.8t[/tex]

George walks to a friend's house. He walks 750 meters North, then realizes he walked
too far. He turns around and walks 250 meters South. The entire walk takes him 13
seconds.
Answers
Answer:
I think you are looking for the velocity, so the answer is 38.5 m/s
Explanation:
Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.
