Answer:

Time taken for the car to travel a distance of 4.50 m = 1.40 seconds

Explanation:

velocity of toy car = 3.21 m/s

distance travelled by toy car = 4.50 m

Time = ?

Velocity = \frac{Distance}{Time} \\Time =\frac{Distance}{Velocity}

Time = \frac{4.50}{3.21} \\Time = 1.40s

Therefore, the time taken for the car to travel a distance of 4.50 m = 1.40 seconds

According to Newton's first law, if an object is slowing down, what must be happening?A.No forces are acting on it.
ira [324]

According to Newton's first law of motion, if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed. Galileo realized the motion of an object doesn't change until an unbalanced force acts on it.

Gravitational force exist between you and the building why are you not pulled towards the building?​
Nataly_w [17]

Answer:

You are pulled towards that building. At the same time, that building is pulled towards you. Neither object creates enough gravitational force to really do anything. That is why you never notice any affect by either body, (you and a building).

Explanation:

You will surely get attracted towards the building.But it takes a lot of time depending on their masses.

This happens only when you are away from earth with that building.

Both of you will get attracted to it

if a third party with mass more than you or building is with you.

If it is on the earth.. Then the gravity between you and the building is negligible compared to the earth.Hence you will not get attracted towards the building in this case.

a toy dart gun generates a dart with .140kg.m/s momentum and a velocity of 4m/s. what is the mass of the dart in grams?
sleet_krkn [62]

Answer: m = 0.035kg = 35g

Explanation: Momentum p=0.140kgm/s

Velocity v=4m/s

Mass m=?

Formula-

Momentum depends on the mass of the object in motion and its velocity.

The equation for momentum is

p = mv

m = p/v

m = 0.140/4

m = 0.035kg

m = 35g

Hence, in the toy dart gun mass of the dart is 0.035kg.

Hello, my younger sister is stuck on this and I just got on here to ask this question. I have my original account but I just mad
nignag [31]

Answer:

Hi there!

I'm sorry your sister is struggling!

I am an edgenuity student in grade 11, I could probably help!

A trend is a line on a graph that all points seem to follow. This is best explained when thinking about line of best fit. If all your points go upward each time and are closed together, we can find the line that gets closest to each point!

Think of a trend as a pattern. The line of best fit, created by analyzing the trends, helps us guess at what the data points beyond what we have will equal

Is there any clarification she needs?
