Explanation

 Torque is the rotational analog of force and equals the rate of change of angular momentum.

Explanation

When the velocity-time graph is a straight line parallel to the time axis then its acceleration is zero.

This is because velocity is constant w.r.t time ie., the change in velocity is zero.

Hence, the acceleration is also zero.

Explanation

 Electromagnetic force is a scalar quantity.

Force is defined as the product of mass and acceleration and force is a vector quantity.

This is the pair in which one physical quantity is scalar and the other is a vector.

Explanation

 Though fluorine is more electronegative, chlorine has the highest electron affinity due to less electron-electron repulsion.

Explanation

The pair of physical quantities with the same dimensions is Work and Energy.           

Both work and energy have the same dimensional formula: ML²T⁻²

Explanation

Newton's Second law of motion:

The rate of change of momentum of any object is directly proportional to the applied force on the body.

Bragged means شیخی مار

Boasted means گھمنڈ

Explanation

This is an arithmetic sequence with:

• First term $a=1$

• Common difference $d=4-1=3$

General formula for the
$n$th term of an arithmetic sequence:

$$T_n = a + (n - 1)d$$

We need the 101st term:

$$$$
T_{101} = 1 + (101 - 1) times 3 = 1 + 100 times 3 = 1 + 300 = boxed{301}

Explanation

Step 1: Use projectile motion

The maximum range of a projectile (ignoring air resistance) is given by:

R=v^2sin(2θ)/g​

The maximum range occurs when θ=45∘the value is maximum at (i.e.,sin(90∘)=1).

Step 2: Plug in values

• $v = 12 text{m/s}$

• g=10 m/s^2

R=12^2⋅1 ​/ 10 

= 144/10

​=14.4 meters
