If runner A is running at 7.50 m/s and runner B is running at 7.90 m/s, how long will it take runner B to catch runner A if runn

yaroslaw [1]

Answer:

t= 137.5 s

Explanation:

So if we are wanting to figure out how long it takes runner B to catch runner A. we must first set the slope of each runner equal to one another

<u>Slopes:</u>

Runner A: y = 7.50x + 55

Runner B: y = 7.90 x

sooooo

7.50 x + 55 = 7.90 x

- 7.50 x - 7.50 x

55 = .40 x

55/.40 = .40 x / .40

x = 137.5 s

t= 137.5 s

7.50 * 137.5 + 55 =1086.25 m

7.90 * 137.5 = 1086.25 m

An eccentric inventor attempts to levitate by first placing a large negative charge on himself and then putting a large positive

GuDViN [60]

Answer:

shirt is little attached to the body, it can come off and fly away

Explanation:

In electrostatics, charges of different signs attract and charges of the same sign repel.

In this case, when a negative charge is placed on it, both the inventor and the shirt are charged, therefore there is a repulsive force, also there is an attraction between the positive charge of the roof attracts the negative charge, such as the shirt. of weak the two forces not greater than the resistance of the walk.

As the shirt is little attached to the body, it can come off and fly away

Why are denser materials found closer to earths center

ICE Princess25 [194]

Denser materials tend to be closer to earths center due to their mass gravity is shown by the equation mg
Which stands for mass x gravity.

Tabitha knows the redshift value of a particular celestial object. What can she use this information most directly to find out?

AlekseyPX

She can use the information of redshift of a celestial body is to find the age and distance of the object.

<h3>What is red shift?</h3>

'Red shift' is a critical idea for astronomers. The frequency of the light is increased, so the light is observed as moving towards the red side of the range.

Tabitha knows the redshift value of a particular celestial object. She uses this information to observe the consequence of the redshift.

Thus, the red shift value is used to determine the age and distance of the object.

2. An archer shoots an arrow at 83.0 m/s at a 62.0 degree angle. If the ground is flat, how much time is the arrow in the air?

UkoKoshka [18]

Answer:

Explanation:

<u>Diagonal Launch </u>

It's a physical event that happens where an object is thrown in free air (no friction) forming an angle with the horizontal reference. The object then describes a path called a parabola.

The object will reach its maximum height and then return to the height from which it was launched. The equation for the height is :

$\displaystyle y=y_o+v_osin\theta \ t-\frac{gt^2}{2}$

Where vo is the initial speed, $\theta$ is the angle, t is the time and g is the acceleration of gravity .

In this problem we'll assume the arrow was launched from the ground level (won't consider the archer's height). Thus $y_o=0$ , and:

$\displaystyle y=v_osin\theta \ t-\frac{gt^2}{2}$

The value of y is zero twice: when t=0 (at launching time) and in t= $t_f$ when it goes back to the ground. We need to find that time $t_f$ by making $y=0$
