Ira Lisetskai [31]

Answer:

Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.

At the instant the traffic light turns green, an automobile starts with a constant acceleration a of 2.70 m/s2. At the same inst

kifflom [539]

Answer:

66.85 m

Explanation:

We are given that

Acceleration ,a= $2.7m/s^2$

Speed of truck, v=9.5 m/s

We have to find the distance beyond which the traffic signal will the automobile overtake the truck.

Initial speed of automobile, u=0

We know that

$s=ut+\frac{1}{2}at^2$

Using the formula

$s=0+\frac{1}{2}(27)t^2=\frac{27}{2}t^2$

For constant speed

Acceleration, a=0

Again

$s=vt+0=9.5t$

$9.5t=\frac{27}{2}t^2$

$t=\frac{9.5\times 2}{2.7}=7.037s$

Substitute the value of t

$x=9.5(7.037)=66.85m$

Hence, the distance beyond which the traffic signal will the automobile overtake the truck=66.85 m
