The density of wood is $0.5gm/cc$ in the CGS system of units. The corresponding value in MKS units is :

1. 500

2. 5

3. 0.5

4. 5000

Which is the correct unit for measuring nuclear radii

1. Micron

2. Millimetre

3. Angstrom

4. Fermi

Volt/metre is the unit of 

1. Potential

2. Work

3. Force

4. Electric field intensity

The velocity of a particle depends upon as $v=a+bt+c{t}^2$; if the velocity is in $m/\sec$, the unit of a will be 

1. $m/\sec$

2. $m/{\sec }^2$

3. $m^2/\sec$

4. $m/{\sec }^3$

If the unit of length and force be increased four times, then the unit of energy is

2. Increased 8 times

3. Increased 16 times

4. Decreased 16 times

The unit of specific resistance is 

1. Ohm / cm²

2. Ohm / cm

3. Ohm - cm

4. (Ohm - cm)^-1

If \(u_1\) and \(u_2\) are the units selected in two systems of measurement and \(n_1\) and \(n_2\) are their numerical values, then:

If $x=at+b{t}^2$, where x is the distance travelled by the body in kilometres while t is the time in seconds, then the units of b are

1. $km\text{}/\text{}s$

2. $km\text{}-\text{}s$

3. $km\text{}/\text{}{s}^2$

4. $km\text{}-\text{}{s}^2$
