minutes?
hey
Answer:
6 mph
Explanation:
mph = miles per hour
So 15 miles over 2.5hrs
So 15/2.5 = 6 mph
How is momentum calculated?
O A. By dividing mass by velocity
B. By subtracting velocity from mass
C. By multiplying mass by velocity
D. By adding mass and velocity
Momentum can be calculated by multiplying the mass of an object by the velocity of an object. Thus, the correct option is C.
What is Momentum?The momentum is a quantity which can be defined as the product of the mass and velocity of an object. It is an example of standard mechanical quantity. Momentum is a vector quantity, this means it possess both a magnitude and a direction. If "m" is an object's mass and "v" is its velocity, then the object's momentum p is:
p = m × v
The examples of momentum is whenever we toss a ball at someone as well as it smacks them square in the face. It indicates how difficult it would have been to stop the ball.
Therefore, the correct option is C.

what are the aerodynamics of a cow
Answer:
32
Explanation:
Answer:
There's nothing quite like placing random objects through some computational fluid dynamics software. As we can see, the forehead of the cow experiences a zone of high pressure, since a lot of the air is deflected from the front of the nose and straight to the head.

How long will it take to travel 84 miles if
you are traveling at a constant 70 miles
per hour?
quick omg ‼️ please
Answer:
The answer is 1.2 hoursExplanation:
To find the time taken given the velocity and distance covered we use the formula
[tex]t = \frac{d}{v} \\ [/tex]
where
t is the time
d is the distance covered
v is the velocity
From the question
d = 84 mi
v = 70 mi/h
We have
[tex]d = \frac{84}{70} = \frac{6}{5} \\ [/tex]
We have the final answer as
1.2 hoursHope this helps you
metals with low resistivity behave as_____
Answer:
At most temperatures, silver has lowest resistivity.
However, superconductors have zero resistivity, which is the lowest. Superconductors are real, they are primarily used in very powerful magnets (such as in CERN). Known superconductors require VERY low temperatures which require expensive technology.
There is ongoing research to find compounds that exhibit room temperature superconductivity. If (when?) one or more is found, major changes to electricity as we know it will result. Not only will we be able to make very powerful magnets (for use in very powerful motors, generators, etc.), but the power companies will be able to move electricity from the generator to the user without loss. Today typical power transmission losses are between 8% and 15%. There may also be important benefits to computer and processing capabilities.
Hope this helps! :D
4) Why is it important to do a warm up with stretching and also a cool down with

In a cinema theatre, why do we normally not hear echoes even though the sounds are loud?
Answer:
An echo is formed as a result of reflection of the original sound which returns to the listener. You might have experienced Echo in an EMPTY ROOM but no echo is produced after the room is occupied. To avoid echo from being produced the echo has to be absorbed.

A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.
Answer: 8.1m/s^2
Explanation:
For this question, in order to solve it, we have to use the second equation of motion which will be:
s = ut + 1/2at^2
where,
u = initial velocity
v = final velocity
t = time
a = acceleration
Since u = 0, then
a = 2s/t^2
a = 2 × 110/5.21^2
a = 220/27.1441
a = 8.1m/s^2

How would you determine the acceleration from a v vs. t graph?
The acceleration is the slope of the v/t graph.
-- If the graph is a straight line, then pick any piece of the line, or even the whole graph, and divide (change in 'y') by (change in 'x') for the piece you chose.
-- If the graph is a curve or a squiggle, then you can do the same thing with a piece of it, and you get the average acceleration during that piece.
-- If you need the acceleration at one point on the graph, you have to lay a straight line against that point on the graph, and find the slope of that straight line.

Spot?
(1) 50 N, 120 W
(3) 25 N, 158 W
(2) 25 N, 158 €
(4) 25 S, 158 E
Answer: (3) 25°N, 158°W
Explanation:
The Hawaii Hotspot is one of the most popular on the planet and is the reason the Hawaii islands were created as it created volcanoes under the Hawaii islands that erupted as the Pacific plate moved over them and then the lava cooled thereby forming the different Hawaii islands.
The approximate location of the hotspot is 25°N, 158°W in the pacific ocean.

Explanation:
A dog walks 40. m west, then 10. m east and then 50. m south. What is the
distance and displacement traveled?
The total distance traveled by the dog is 100 m and the displacement of the dog is 58.31 m.
The given parameters;
Initial position of the dog, 40 m westSecond position of the dog, 10 m eastFinal position of the dog, = 50 southThe displacement of the dog is the change in its initial position and the final position.
The resultant of the dogs position in x-direction: = 40 m - 10 m = 30 m
The resultant of the dogs position in y-direction: 50 m
The magnitude of the displacement;
R² = 30² + 50²
R² = 3400
R = √3400
R = 58.3 m
The distance covered by the dog is the sum of all the positions of the dog.
Distance = 40 m + 10 m + 50 m
Distance = 100 m.
Thus, the total distance traveled by the dog is 100 m and the displacement of the dog is 58.31 m.

A golfer pulls on the eighteenth green at a distance of 5.0m from the hole. The ball rolls straight. In the positive direction, but overshoots the hole by 1.2m. The golfer then putts back to the hole and sinks the putt for par. What is the displacement of the ball?
Answer:
Explanation:
The initial position of the ball = - 5 .0 m from the hole .
It is negative because , direction towards the hole is positive so direction from the hole will be negative .
Final position of the ball = 0 m from the hole .
Displacement of the ball = Final position - Initial position
= 0 - ( - 5 ) = 5 .0 m
Displacement = + 5 m
A pen cap floats in a plastic lemonade 3/4 full of water vif you squeeze the bottle the pen cap sinks to the bottom if you then let go of the bottle the pen cap floats to the surfce whe the bottle squeezed what ,if anything happens to the distance between the air molecules inside the bottle????????/
Answer:
The pressure of the air molecules inside the pen cap increases and the volume occupied by the air decreases such that the combined volume occupied by the pen cap and the air volume reduces while the combined mass of the pen cap and the air molecules remain the same
Given that density = The mass/Volume, we have that the density varies inversely as the volume, and as the volume reduces, the density increases
Upon squeezing, therefore, as the new combined density of the pen cap and the air molecules rises to more than the density of the water in the bottle, then, the pen cap air molecule is relatively more denser than the water, which will result in the pen cap sinking to the bottom of the bottle
