25.	A bus starting from rest masses with a uniform acceleration of 2 m/s for 4 minutes. a)find the speed acquired. b)find the distance travelled
Answer» GIVEN : Initial velocity, u = 0 m/s. Acceleration, a = 2 m/s². TIME, t = 4 min. TO FIND : Speed, v = ? DISTANCE travelled, d = ? CONCEPTS USED : Newton's first law of motion. Newton's third law of motion. SOLUTION : To find the speed, v = ? Using the Newton's first equation of motion, V = u + at. Substitute the given values in the above equation. $\implies$ V = 0 + 2 × 240 $\implies$ V = 0 + 480 $\large \fbox \red {\sf Speed \ = \ 480 \ m/s}$ •°• Therefore, the speed acquired is 480 m/s. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Now, To find the distance travelled = ? Using the third equation of motion, S = ut + 1/2 at² Substitute the given values in the above equation. $\implies$ S = 0 × 240 + 1/2 × 2 × 240 × 240. $\implies$ S = 0 + 57600 $\large \fbox \red {\sf Distance \ = \ 57600 \ m}$ •°• Therefore, the distance travelled is 57600 meters. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

A bus starting from rest masses with a uniform acceleration of 2 m/s for 4 minutes. a)find the speed acquired. b)find the distance travelled

Answer»

GIVEN :

Initial velocity, u = 0 m/s.
Acceleration, a = 2 m/s².
TIME, t = 4 min.

TO FIND :

Speed, v = ?
DISTANCE travelled, d = ?

CONCEPTS USED :

Newton's first law of motion.
Newton's third law of motion.

SOLUTION :

To find the speed, v = ?

Using the Newton's first equation of motion,

V = u + at.

Substitute the given values in the above equation.

$\implies$ V = 0 + 2 × 240

$\implies$ V = 0 + 480

$\large \fbox \red {\sf Speed \ = \ 480 \ m/s}$

•°• Therefore, the speed acquired is 480 m/s.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Now,

To find the distance travelled = ?

Using the third equation of motion,

S = ut + 1/2 at²

Substitute the given values in the above equation.

$\implies$ S = 0 × 240 + 1/2 × 2 × 240 × 240.

$\implies$ S = 0 + 57600

$\large \fbox \red {\sf Distance \ = \ 57600 \ m}$

•°• Therefore, the distance travelled is 57600 meters.

26.	Explain and derive equation for division of current in parallel circuits
Answer» Answer: We can check our calculations as according to KIRCHHOFF's CURRENT Rule, all the branch CURRENTS will be equal to the total current, so: IT = IR1 + IR2 + IR3 = 10 + 4 + 1 = 15 amperes, as expected. Thus we can see that the total current, IT is divided according to a simple ratio determined by the branch resistances.
