The distance traveled by plane flying at 1200 Km/h for 2.5 hours is 3000 Km.

Velocity is a vector quantity. It has both a direction and a magnitude. Speed is used to calculate the magnitude of velocity. The meter per second is the S.I. unit for this. The units km/h and km/s are additional units. [LT-1] is the dimensional equation for it.

The distance traveled by the object is calculated as the product of the velocity with which it was moving and the time interval for which the distance covered is calculated.

Distance traveled =  Velocity × Time

Given in the question

Velocity of the plane = 1200 Km/h

Time Traveled = 2.5 h

Put in the value, we get

Distance traveled =  1200 × 2.5

Distance traveled = 3000 Km

Hence, the distance traveled by plane flying at 1200 Km/h for 2.5 hours is 3000 Km.

What is the strength of electric field EpEp 0.60 mmmm from a proton? Express your answer to two significant figures and include
disa [49]

Answer:

3.99*10^-3N/C

Explanation:

Using

Ep= kq/r²

Where r = 0.6mm = 0.6*10^-3m

K= 8.9*10^9 and q= 1.6*10^-19

So = 8.9*10^9 * 1.6*10^-19/0.6*10^-3)²

= 3.99*10^-3N/C
