Answer:

i think it's weakest

EDIT: It's net. I answered weakest but it was wrong and the correct answer was net. oops

Explanation:

if a strong force is acting on something it will push it away, meaning the object would go towards the weaker force

An object will move towards the strongest force.

Answer: Option B

<u>Explanation: </u>

Based on Newton's first law, an object will remain in its rest state or motion unless an some external forces act on it. The external force can be a balanced or unbalanced force.

The balanced forces act on an object with equal magnitudes but in opposite direction, so the net force will be zero. But unbalanced forces are the forces where the net forces on the object is not zero.

The best example for this is tug of war. Here, the tug will go towards the team who will pull with greater magnitude of force. Thus, the object will move towards the direction of strongest force among all on the unbalanced forces acting on the object.

someone help pls. Two students, Mia and Peter, leave school to meet at the local coffee shop. Peter decides to jog to the coffee

cluponka [151]

Answer:

1) The distance further it takes Peter to arrive at the Coffee shop than Mia is 1.24 km

2) Mia's average speed is 6.00 km/hour

Peter's average speed is 8.48 km/hour

4) Mia's average velocity = Peter's average velocity = 6.00 km/hour

Explanation:

The given information from the diagram are;

The distance Peter jogs from school to the flower shop = 2.00 km

The distance Peter jogs from the Flower shop to the Coffee shop = 2.24 km.

The distance Mia walks from school directly to the Coffee shop = 3.00 km

The time it takes both Peter and Mia to arrive at the coffee shop = 30 minutes = 0.5 hour

1) The total distance Peter travels from school to the Coffee shop = 2.00 km + 2.24 km = 4.24 km

The distance Mia travels from school to the Coffee shop = 3.00 km

The distance further it takes Peter to arrive at the Coffee shop than Mia = 4.24 km - 3.00 km = 1.24 km

The distance further it takes Peter to arrive at the Coffee shop than Mia = 1.24 km

2) $Average \ speed = \dfrac{Total \ distance \ traveled}{Total \ time \ taken \ in \ the \ journey}$

$Therefore, \ Mia's \ average \ speed = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour$

Mia's average speed = 6.00 km/hour

$Peter's \ average \ speed = \dfrac{4.24 \ km}{0.5 \ hour}= 8.48 \ km/hour$

Peter's average speed = 8.48 km/hour

4) $Average \ velocicty = \dfrac{Displacement }{Time \ taken}$

The displacement from the School to the Coffee shop is 3.00 km for both Mia and Peter

The time it takes both Peter and Mia to arrive at the Coffee shop from the school is 30 minutes = 0.5 hour

$Therefore, \ Mia's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour$

Mia's average velocity = 6.00 km/hour

$Peter's \ average \ velocity = \dfrac{3.00 \ km}{0.5 \ hour}= 6.00 \ km/hour$

Therefore, Peter's average velocity is also = 6.00 km/hour

If the speed of a motor scooter doubles, which of the following also doubles? 1)kinetic energy 2) acceleration 3) momentum 4) al

emmasim [6.3K]

Answer:

Explanation:

-The formula for kinetic energy is the following:

K.E.= $\frac{1}{2}$ m $v^{2}$

where:

K.E. is kinetic energy

m is mass

v is velocity

Here we can see that kinetic energy is proportional to the velocity squared, so if the speed or velocity of the scooter doubles then this would quadruple its kinetic energy.

-The acceleration is the rate of change of velocity per unit of time. A scooter could double its speed with a constant acceleration, so an increase in speed doesn't necessarily mean an increase in acceleration.

-The formula for momentum is the following:

p=mv

where:

p is momentum

m is the mass of the object

v is the objects velocity

Here we can see that the momentum is directly proportional to the velocity, so if the scooter where to double its velocity then it would also double its momentum.
