The magnitude of a velocity vector is 60 m/s.
To find the magnitude, the given values are,
x - components = 36 m/s
y - components = 48 m/s
<h3>What is magnitude?</h3>
- The term magnitude can be defined as “ quantity ”.
- For instance, the magnitude can be used for describing about the comparison of speeds.
- It can also be used to explain the distance travelled by an object or to explain the amount of an object in terms of its magnitude.
- Magnitude of the velocity vector is total value which is square root of the value.
The magnitude of the vector can be,
| a | = √ ( x² + y² )
Substituting the values of x component and y component given,
= √ ( 36² + 48² )
= √ ( 1296 + 2304)
= √ 3600
= 60 m/s
The magnitude is found to be 60 m/s.
Hence, Option B is the correct answer.

The object will fall toward Earth faster. bcz, the Earth got gravity
Answer:
Because Moon and Mars has no atmosphere.
Explanation:
Moon and Mars has no atmosphere, so there is no friction on the falling object due to the atmosphere. The speed of the falling object is more at Moon and Mars.
When a small object impact on the surface of moon or Mars with high speed, the size of crater is large than the earth as out earth has atmosphere.
<span>The electrons need to migrate from a region of lower electric potential to a region of higher electric potential. This flow of electrons is known as electron current (which is contrary to the widely-accepted perspective of conventional current).</span>
Answer:
1. A
2. C
3. A
4. B
Explanation:
A conductor allows electric current to pass through it. Hence, when conductors are connected in a closed circuit, current flows.
All the resistors in Q2 are connected in series. In a series connection, the current across all the resistors is the same.
In a battery, chemical energy is converted to electrical energy by chemical reactions.
When a new resistor is connected in parallel to a circuit the current increases accordingly.
