What are 3 criteria for acceleration?

1 answer:

Temka [501]4 years ago

3 0

I don't think you mean 'criteria'. I think you mean three occurrences or
observations that indicate the presence of acceleration.

They are:

-- an object is speeding up
-- an object is slowing down
-- the direction of an object's motion is changing .

Any one of these changes is acceleration.

There's a single term that covers them all. It is "change in velocity".

What is the orbital period in years of a planet with a semi major axis of 35 au

mezya [45]

Answer:

Orbital period of the planet will be 207.06 year

Explanation:

We have given the planet have the semi major axis as 35 au

We have to find the orbital period of the planet

From Keplar's third law there is relation between the orbital period and semi major axis which is t $T^2=R^3$

So $T^2=35^3$

$T^2=42875$

$T=207.06year$

So orbital period of the planet will be 207.06 year

Two spheres carry a charge of 1x10^-7 C. Their centers are separated by 0.7m. Calculate the magnitude of the force between the t

Drupady [299]

We have that the force between the two charged objects is mathematically given as

F=2.349N

<h3>Magnitude of the force between two charged objects.</h3>

Question Parameters:

Two spheres carry a charge of 1x10^-7 C.

Their centers are <u>separated</u> by 0.7m.

Generally the equation for the Force is mathematically given as

$F=\frac{q1q2}{4*\pi e*r}$

Therefore

$F=\frac{(1e-7)^2}{9e9*0.7}$

F=2.349N

When you see a quantity like 20 m/s N, how do you know that it's a vector quantity and not a scalar quantity?

KengaRu [80]

We know that 20 m/s N is a vector quantity because N in the expression signifies the direction

<h3>What is a vector quantity?</h3>

This is a which have both magnitude and direction. Example include:

Velocity
Displacement
Force
Acceleration
Moment
Weight

<h3>How to determine whether 20 m/s N is a vector quantity</h3>

20 m/s indicates just the speed i.e magnitude
20 m/s N indicates the speed i.e magnitude why the N indicates the direction.

Thus, we can conclude that 20 m/s N is a vector quantity because it has both magnitude and direction.
