a box has a length of .5 m and a width of .1m. if the box exerts a force of 10 N on the floor, what is the pressure of the box on the floor
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

A car drives 215 km west and then 85 km south. Find the distance and displacement of the car.
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.
What is displacement?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.

A plane mirror moves towards the object with a velocity of 2m/s and the object itself moves towards the mirror with a velocity of 5m/s. What is the velocity of the image approaching towards the object..
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

If a metal has a mass of 78.2 g and a volume of 11.4 mL, what is its density?
Answer:
6.86g/mL
Explanation:
The density of the metal would be approximately 6.859 grams per milliliter (g/mL).
Given that the mass (m) is 78.2 g and the volume (V) is 11.4 mL, we can plug these values into the formula:
Density is a physical property that quantitatively expresses how much mass is contained within a given volume of a substance. In other words, it is a measure of how tightly packed the particles or molecules of a material are. Mathematically, density is defined as the mass of an object (or substance) divided by its volume. It is often denoted by the Greek letter "ρ" (rho).
Density is defined as mass per unit volume. The formula for density is:
Density (ρ) = Mass (m) / Volume (V)
Density (ρ) = 78.2 g / 11.4 mL
Now, let's calculate the density:
Density (ρ) = 6.859 g/mL
So, the density of the metal is approximately 6.859 grams per milliliter (g/mL).

A treasure map directs you to start at palm tree
and walk due north for 15.0 m. You are then to turn
90° and walk 22.0 m; then turn 90° again and
walk 5.00 m.
Give the distance from the palm tree,and the direction to north, for each of the four possible locations of the treasure .
The direction of the 90° turns are the possible directions used for the calculations
The four distances and directions are;
24.2 m, 65.6° West of North29.7 m, 42.7° East of North24.2 m, 65.6° East of North29.7m, 47.7° West of NorthReason:
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)

Therefore, we have;

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)

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

A man is on a 30m cliff and throws a ball down with a speed of 7 m/s.
A) With what velocity does the ball hit the ground? B) How high above the ground is the ball after the ball has fallen for 1 second?
Answer:
210
Explanation:
A ball rolls horizontally off the cliff at a speed of 30 m/s. It takes 7 seconds for the ball to hit the ground. What is the height of the cliff and the horizontal distance traveled by the ball?
S = (1/2)*9.8 m/s^2 * 7^2 = 240.1 m if the ball is very dense so air resistance, and therefore terminal velocity, can be ignored.
S = v * t = 30 m/s * 7 s = 210 m for the horizontal distance, again assuming negligible air resistance.
Height above the ground is the ball after the ball has fallen for 1 second is 210 m.
What is speed?The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
A ball rolls horizontally off the cliff at a speed of 30 m/s. It takes 7 seconds for the ball to hit the ground.
S = (1/2)*9.8 m/s² * 7² = 240.1 m if the ball is very dense so air resistance, and therefore terminal velocity, can be ignored.
S = v * t = 30 m/s * 7 s = 210 m for the horizontal distance, again assuming negligible air resistance.
