The Direction of the Velocity Vector

Objects moving in uniform circular motion will have a constant speed. Velocity, being a vector, has both a magnitude and a direction. The magnitude of the velocity vector is the instantaneous speed of the object.

Answer:

Different classes of levers

Explanation:

The main difference between a pair of scissors and nailcutters is that they are different classes of levers. Scissors are made from two class 1 levers, meaning that the effort is exerted at one end and the load at the other with the fulcrum in the middle. This is because we press one end together (the handles) so we are applying the effort, and the other side closes from the fulcrum in the middle.

Nailcutters on the other hand, consist of two class 2 levers. This means that the fulcrum is on the opposite end to the effort with the load in the middle. This is because we press down on one side and the two parts move closer together.

Answer:

It will maintain its state of motion

Explanation:

The object would maintain its state of motion.

If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.

Equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.

They don't have directions.

The quantities with only magnitude and no direction are called scalar quantities. Therefore, option D is the correct answer.  

Scalar quantities have only magnitude but vector quantities have both magnitude and direction. Some examples of scalar quantities are,

• Mass

• Temperature  

• Speed

• Density

Thus, we conclude that the quantities with only magnitude and no direction are scalar quantities. Hence option D is the correct pair.

It is defined as motion when the object is moving in a circle with a constant speed and its velocity is changing with every moment because of the change of direction but the speed of the object is constant in a uniform circular motion

Hence,  runners sprinting across a straight track is a type of linear motion, the propeller of an aircraft in midair is performing the rotational motion, a car driving up a winding mountain road is a curvilinear motion, music being played on a stringed instrument, such as a guitar is a type of vibrational motion

Answer:

Explanation:

Given data

the radius of curve= 90m

speed v= 90 km/h to m/s = (90*100)/60*60=  25 m/s

we know that the expression for the centripetal force acting on the car

[tex]Fc= \frac{mv^2}{r}[/tex]-------1

we also know that the expression for the frictional force between road and tire.

Ff= μmg--------2

μmg= mv^2/r

μ= v^2/gr

Explanation:

this question is in biology not physics

Answer:

A.) 4.81 seconds

B.) 44.6 m/s

Explanation:

He begins his dive by jumping up with a velocity of 5 (m/s).

Let us first calculate the maximum height reached by using third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

0 = 5^5 - 2 × 9.8H

19.6H = 25

H = 25 /19.6

H = 1.28 m

The time taken for the diver to reach the water from the maximum height can be calculated by using second equation of motion.

Where height h = 1.28 + 100 = 101.28 m

h = Ut + 1/2gt^2

As the diver drop from maximum height, U = 0

101.28 = 1/2 × 9.8 × t^2

4.9t^2 = 101.28

t^2 = 101.28/4.9

t^2 = 20.669

t = sqrt ( 20.669)

t = 4.55s

As the diver jumped up, the time taken to reach the maximum height will be

Time = 1.28 / 5 = 0.256

The time taken for him to hit the water below will be 0.256 + 4.55 = 4.81 seconds

B.) Velocity right before he hits the water will be

V^2 = U^2 + 2gH

But U = 0

V^2 = 2 × 9.8 × 101.28

V^2 = 1985.09

V = 44.6 m/s

A.) The time taken should be 4.81 seconds

B.) The velocity should be 44.6 m/s

Here we used third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

Now

0 = 5^5 - 2 × 9.8H

19.6H = 25

H = 25 /19.6

H = 1.28 m

Here the second equation of motion.

Here height h = 1.28 + 100 = 101.28 m

So,

h = Ut + 1/2gt^2

Since the diver drop from maximum height, U = 0

So,

101.28 = 1/2 × 9.8 × t^2

4.9t^2 = 101.28

t^2 = 101.28/4.9

t^2 = 20.669

t = sqrt ( 20.669)

t = 4.55s

Now

Time = 1.28 / 5 = 0.256

Finally the time should be

=  0.256 + 4.55

= 4.81 seconds

B.)

We know that

V^2 = U^2 + 2gH

But U = 0

So,

V^2 = 2 × 9.8 × 101.28

V^2 = 1985.09

V = 44.6 m/s
