Write S if the given quantity is scalar and V if the quantity is a vector
VikaD [51]

Answer:

1. Scalar_100° Celsius

2. Vector_50 m/s²

3. Scalar_300 s

4. Vector_250 m/s, northwest

5. Vector_1m, to the right

6. Vector_10 cm, upwards

7. Scalar_525 600 mins.

8. Vector_90 km/h,east

8. Scalar_5 000 kg

10. Scalar_1.5 L

Explanation:

A scalar quantity can be defined as a quantity that has magnitude but no direction. Some examples of scalar quantities are speed, mass, temperature, volume, length, etc.

On the other hand, a vector quantity has both magnitude and direction. Some examples of vector quantities are acceleration, velocity, displacement, etc.

1. Scalar_100° Celsius (Temperature).

2. Vector_50 m/s² (Acceleration).

3. Scalar_300 s (Time).

4. Vector_250 m/s, northwest (Velocity).

5. Vector_1m, to the right (Displacement).

6. Vector_10 cm, upwards (Displacement).

7. Scalar_525 600 mins. (Time).

8. Vector_90 km/h,east (Velocity).

8. Scalar_5 000 kg (Mass).

10. Scalar_1.5 L (Volume).

A mover pushes a 46.0kg crate 10.3m across a rough floor without acceleration. How much work did the mover do (horizontally) pus
Alchen [17]

Answer:

<h3>2,321.62Joules</h3>

Explanation:

The formula for calculating workdone is expressed as;

Workdone = Force * Distance

Get the force

F = nR

n is the coefficient of friction = 0.5

R is the reaction = mg

R = 46 ( 9.8)

R = 450.8N

F = 0.5 * 450.8

F = 225.4N

Distance = 10.3m

Get the workdone

Workdone = 225.4 * 10.3

Workdone  = 2,321.62Joules

<em>Hence the amount of work done is 2,321.62Joules</em>

What is the resistance of a 15 ampere current with 8 volts of potential difference?
Alex Ar [27]

Answer:

Resistance in circuit = 0.53 ohm (Approx.)

Explanation:

Given:

Flow of current in circuit = 15 amp

Potential difference = 8 Volts

Find:

Resistance in circuit

Computation:

In an electrical system, resistance is a stopper of a material to electric current.

Resistance in circuit = Potential difference / Flow of current in circuit

Resistance in circuit = 8 / 15

Resistance in circuit = 0.53 ohm (Approx.)
