<u>Answers</u>

1) Reaction

2) Gravitational force

3) Frictional force


<u>Explanation</u>

Reaction is directly opposite and equal to action(normal force). The normal force is the weight. So we can say that reaction supports the weight of the car.

Objects fall downwards due to acceleration due to gravity. The acceleration force is provided by the gravitational force. The car is accelerated downwards by the gravitational force.

Frictional force is the force that opposes relative motion between two bodies. When iar is involved, we call it viscosity. So the force that acts against the motion of the car is friction.

If you are given distance and a period of time what can you calculate
Digiron [165]

If you are given distance and a period of time, you can calculate the speed. The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion (e.g. 60 km/h to the north).

A 1.5m wire carries a 7 A current when a potential difference of 87 V is applied. What is the resistance of the wire?
kramer

Answer:

Ohm's law states that I=V/R (Current=volts divided by resistance). Since we're looking for resistance, we'll rewrite it as R=V/I. Then just plug in the numbers; R=84/9, R= 9 1/3 or 28/3. The resistance of the wire is 9.33... or 9 1/3 ohm's, depending on how you wanna write it.

Hope it helped u if yes mark me BRAINLIEST!

Tysm!

I would appreciate it!

IRINA_888 [86]

The US Supreme Court has affirmed in Miller v. Johnson (1995) that racial gerrymandering is a violation of constitutional rights and upheld decisions against redistricting that is purposely devised based on race. However, the Supreme Court has struggled as to when partisan gerrymandering occurs (Vieth v.

What is the definition of Mutualism
noname [10]
Mutualism is a long-term relationship where two organisms interact in such a way that both of them benefits from that relationship.

For example, there is a relationship between a bird called "oxpecker", and a rhino. While the bird eats the harmful bugs (eg. tick) on the rhino's skin and relieves its hunger; the rhino gets rid of the bugs that harm it.
