Answer:

Vector

Explanation:

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude.

What is the direction of the electric force exerted by paperclip 1 on paperclip 2?

Tema [17]

In general, the electric force in an electric field is exerted outward from a positive atom, and inward for the negative atom. Therefore based on the figure you specified, we can say that the electric force exerted by paperclip 1 on paperclip 2 is repulsive.

How fast does water flow from a hole at the bottom of a very wide, 7.1 mm deep storage tank filled with water

trapecia [35]

Answer:

<h2>The water will move faster</h2>

Explanation:

This happens as part of the consequences of the continuity of an incompressible fluid, of which water is an example.

so as the water emerges from the wider section the flow velocity increases and vice versa.

Hence the flow velocity in indirectly proportional to the area

The continuity equation is given below for our analysis

$A1V1=A2V2\\$ -------------------1

where

A1= the area of the wider section of the tank

V1= the flow velocity from the wider section

A2= the area of the hole at the bottom

V2= velocity of flow at the bottom.

A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the va

zloy xaker [14]

Answer:

The value of work being done on the object is 958J.

Explanation:

Work done is equal to force multiply by distance, but when the angle is between the force and distance work done=Force (cos theta) × distance

Work done = Force(cos theta) × distance

Work done = 25N(cos 40.0°) × 50m

Work done = 25N(0.7660) × 50m

Work done = 19.15N × 50m

Work done = 957.5J = 958J

Therefore the value of work being done on the object is 958J.

A skydiver has reached terminal velocity—she now falls at a constant speed, so her acceleration is zero. Is there a net force on

Taya2010 [7]

Answer:

No, the net force on the skydiver is zero

Explanation:

According to Newton's Second Law, the net force on an object is equal to the product between the mass of the object and its acceleration:

$F=ma$

where

F is the net force

m is the mass of the object

a is the acceleration

In this problem, the acceleration of the skydiver is zero:

a = 0

This implies that also the net force on the skydiver is zero, according to the previous equation:

F = 0

So, the net force on the skydiver is zero. This occurs because the air resistance, which points upward, exactly balances the force of gravity on the skydiver, acting downwards.
