Answer:
a. x=5355m b. food
Explanation:
A wave is a disturbance wic travels through a medium, it transfers energy without the displacement of the medium itself.
the problem can be solved with this formula v
v=2x/t
v=speed of the ultrasonic wave in seawater
x=te distance between the seawater surface and the seawater bed
t=time it takes to travel to and fro te seawater bed to the surface
v= 1530 m/s, t=7 s , x=?
1530=2x/7
1530*7=2x
x=5355m
b. An example of stored h energy is food, petroleum etc.Chemical energy are Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; called exothermic.
Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds. we eat food so that we can h enough energy to carry out our day to day task.
The component of the total velocity in the x - direction is 6.96 m/s.
The component of the total velocity in the y - direction is 2.95 m/s.
<h3>
Component of the velocity in x direction </h3>
The component of the total velocity in the x - direction is calculated as follows;
v(x) = vtot cosθ
where;
- vtot is total velocity
- v(x) is velocity in x direction
v(x) = 7.56 x cos(23)
v(x) = 6.96 m/s
<h3>
Component of the velocity in y - direction</h3>
v(y) = vtot sinθ
v(y) = 7.56 x sin(23)
v(y) = 2.95 m/s

False, because I doesn’t matter if there is noise pollution the child will still able to learn the way words work
Answer: 20496N
Explanation:
The formula to calculate the net force will be given as:
Net force = Acceleration × Mass
Since 10248 kg car is pulled by a low tow truck that has an acceleration of 2.0m/s, the net force would be:
= 10248 × 2
= 20496N
