Answer:

B. Chemical energy -> Thermal energy

Explanation:

the candle burning is a chemical reaction where the fire is using the oxygen in the air and the chemicals in the wick and it ends with giving off thermal energy. thermal energy is heat energy.

(this might not be right, i'm 95% sure it is though)

You place an object 36.0 cm in front of a concave

vivado [14]

Given  :

Object position ( u ) = - 36 cm
focal length ( f ) = - 16 cm
image position ( v ) = ?

now, we know

=》

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$

=》

$\frac{1}{ - 16} = \frac{1}{ - 36} + \frac{1}{v}$

=》

$\frac{1}{v} = \frac{ - 1}{16} - \frac{ - 1}{36}$

=》

$\frac{1}{v} = \frac{ - 9 - ( - 4)}{144}$

=》

$\frac{1}{v} = \frac{ - 9 + 4}{144}$

=》

$\frac{1}{v} = \frac{ -5}{144}$

=》

$v = \frac{144}{ - 5}$

=》

 $v = - 28.8$ 

So, image position = 28.8 cm, at same side of object .

2) A car travels 5 miles north, and then 10 miles south. What is the person's DISTANCE and

Liono4ka [1.6K]

Answer:

distance traveled is 15 mi

displacement is 5 mi

Explanation:

Distance takes time into account and adds up all the tiny displacements during the entire period of the trip.

Displacement ignores time and looks only at the change in position from the starting point to the ending point.

A drag racing vehicle travels from 0 to 100mph north in 5 seconds. What is the acceleration

kap26 [50]

The acceleration of the car is $8.9 m/s^2$

Explanation:

The acceleration of an object is given by

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time elapsed

Here we have to convert the initial and final velocity of the vehicle into SI units. So we have:

$u = 0$ is the initial velocity

$v=100 mph \cdot \frac{1609 m/mi}{3600 s/h}=44.7 m/s$ is the final velocity

t = 5 s is the time elapsed

Solving for a, we find the acceleration:

$a=\frac{44.7-0}{5}=8.9 m/s^2$
