Four different blocks are resting on the floor. They each have a different mass, and they are each made of a different material, so the coefficients of friction are not the same. Using the information in the table below, rank, from highest to lowest, the magnitude of the maximum horizontal force

Answer:

The pressure of the box on the floor is 200 Pa

Explanation:

Given,

Length of the box=0.5m

Width of the box= 0.1m

∴Area of the box, A= (0.5 X 0.1) sq.m

                                = 0.05 sq.m

We know,

Pressure, P= F/A

                  = 10/0.05 Pa

                  = 200 Pa

∴The pressure of the box on the floor is 200 Pa

use the formula a=v-u

t

Find the distance traveled by a car that travels with an average speed of 110 km/h for 3.5 h

To solve for distance:

d = v t

d = 110 × 3.5

d = 385 km

How long does it take a baseball moving with an average speed of 35 m/s to travel 18 m?

To solve for time:

t = d/v

t = 18 / 35

t = 0.514286

t = 0.5 s

What is the average speed of a car that travels 870 km in 14.5 h?

To solve for average speed:

v = d/t

v = 870 / 14.5

v = 60 km/h

The direction of the 90° turns are the possible directions used for the calculations

The four distances and directions are;

Reason:

Let point A represent the motion of the treasure hunter, we have:

Turning West then West;

Walking due north to location (0, 15)

Turn 90° West and walk 22.0 m to the location (-22, 15)

Turn 90° West again and walk 5.00 m. to the location (-22, 10)

The location of point A = (-22, 10)

[tex]Direction \ of \ point \ A = arctan \left(\dfrac{10}{-22} \right) \approx -24.4^{\circ}[/tex]

Direction to North = 90° - 24.4° ≈ 65.6°

Distance = √((-22)² + 10²) ≈ 24.2

Therefore, we have;

Turning East then West:

Turn 90° East and walk 22.0 m to the location (22, 15)

Turn 90° West again and walk 5.00 m. to the location (22, 20)

The location of point A = (22, 20)

[tex]Direction \ of \ point \ A = arctan \left(\dfrac{20}{22} \right) \approx 42.7^{\circ}[/tex]

Direction to North = 90° - 42.3° ≈ 47.7° East

Distance = √((-22)² + 20²) ≈ 29.7

Therefore, we have;

Turning East then East:

Turn 90° East and walk 22.0 m to the location (22, 15)

Turn 90° East again and walk 5.00 m. to the location (22, 10)

The location of point A = (22, 10)

[tex]Direction \ of \ point \ A = arctan \left(\dfrac{10}{22} \right) \approx 24.4^{\circ}[/tex]

Direction to North = 90° - 24.4° ≈ 65.6° East

Distance = √((-22)² + 10²) ≈ 24.2

Therefore, we have;

Turn 90° West and walk 22.0 m to the location (-22, 15)

Turn 90° East and walk 5.00 m. to the location (-22, 20)

Answer:

Distance= 300 km

Displacement= 130

Explanation:

When you find distance you have to add

When you find displacemnet you subtract

If a car drives 215 kilometers west and then 85 kilometers south, then the distance and displacement of the car would be 300 kilometers and kilometers respectively.

Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.

As given in the problem, if a car drives 215 kilometers west and then 85 kilometers south, then we have to find the distance and displacement of the car,

The distance traveled by car = 215 kilometers + 85 kilometers

                                                = 300 kilometers

The displacement covered by the car = √(215² + 85²)

                                                               = 231.2 Kilometers

Thus, the distance traveled by car would be 300 Kilometers and the displacement would be 231.2 Kilometers in the southwest direction.

Answer:

3.33 m/s

Explanation:

1/2 = 1/5 + 1/x

1/x = 1/2 - 1/5

1/x = 5/10 - 2/10

1/x = 3/10

x = 10/3

x = 3.33 m/s

#LearnWithEXO

Answer is 4 m/s

Let :-

Constant velocity = v

Time (t) = 2 seconds

Height (h) = 16 metres

As the raindrop has constant velocity, we can write that :

[tex] \frac{h}{2} = vt[/tex]

Substituting the values, we get,

[tex] \frac{16}{2} = v \times 2[/tex]

[tex]8 = v \times 2[/tex]

[tex] \frac{8}{2} = v[/tex]

[tex]v = 4 \: m/s[/tex]

Therefore, the velocity of the raindrop is 4 m/s.
