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).

2. What is the structure of electric circuits? Can a branch of a circuit contain three elements? Can there be a branch which doe

ddd [48]

First electric circuit means, the circuit has elements like resistors, capacitors, and inductors along with sources. Any electric circuit comprises nodes, branches, and meshes.

The joining point of two elements is called a node. The element between two nodes is called a branch. In branch, only one series element is possible to connect but in parallel, it can have N number of elements. No branch without elements in electric circuits.

A resistor is an electrical aspect that limits or regulates the go with the flow of electrical modern-day in a digital circuit. Resistors can also be used to offer a selected voltage for an energetic device together with a transistor.

The resistor is described as. A passive electrical issue with two terminals that can be used for both limiting or regulating the glide of electric contemporary in electric circuits. the main cause of the resistor is to lessen the modern-day go with the flow and to lower the voltage in any unique part of the circuit.

A resistor works by using proscribing the float of current, it may try this in one in all 3 approaches: first off, by using a much less conductive cloth, secondly by making the conductive fabric thinner, and sooner or later by making the conductive fabric longer.

Consider the case in which the clay is launched along Path Y. The sphere of clay is launched with an initial velocity of v0 and

Helen [10]

Answer:

w = $\frac{m}{ml^2 + I R^2 }$ v l

Explanation:

Let's form a system formed by the clay sphere and the rod, in this case the angular momentum is conserved

initial instant. Before the crash

L₀ = m v l

Final moment. After the collision with the clay stuck to the rod

L_f = I_{total} w

angular momentum is conserved

L₀ = L_f

m v l = I_total w

w = $\frac{m}{I_{total} }$ v l

the total moment of inertia is the sum of the moments of inertia of the two bodies

the moment of inertia of the rod is

I_rod = I R²

I_total = m l² + IR²

we substitute

w = $\frac{m}{ml^2 + I R^2 }$ v l
