Answer:
For a solar eclipse to occur the moon must be between the earth and the sun (the light of the sun is blocked)'
By definition this is a new moon (which occurs when the moon cannot be seen because it is located between the sun and the earth).
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)
[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;
24.2 m, 65.6° West of NorthTurning 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;
29.7 m, 42.7° East of NorthTurning 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;
24.2 m, 65.6° East of NorthTurning West then East:
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)

Explanation:
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
Question:
the distance of the car can move by velocity 15 m/s for time 5s is :
Physics
Answer:
c) 2.05
Explanation:
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.

It took the raindrop 2seconds to fall half the distance to the ground. What was the raindrop's velocity?
what is the answer
Answer is 4 m/s
Step-by-step explanation:-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.

*Average Speed v = d/t
Distance d = v t
Time t = d/v
* remember v = average speed
Solve the following problems for average speed, distance or time. Round to tenths place:
Find the distance traveled by a car that travels with an average speed of 110 km/h for 3.5 h.
How long does it take a baseball moving with an average speed of 35 m/s to travel 18 m?
What is the average speed of a car that travels 870 km in 14.5 h?
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
