Answer:
The speed traveled by the car is 40 meter per second.
Explanation:
The formula for the relation between the power and the force is as follows:
P = Fv
Where F is the force and v is the speed.
As given
To travel at constant speed, a car engine provides 24KW of useful power. The driving force on the car is 600N.
F = 600 N
Convert power from KW to W.
1 KW = 1000 W
24 KW = 24 × 1000 W
= 24000 W
Thus
P = 24000 W
Put these values in the formula.
24000 = 600 × v
24000 = 600v

v = 40 meter per second .
Therefore the speed of the car is 40 meter per second .
Answer:
1.4m/s
Explanation:
Average velocity is the total distance covered divided by the total time taken.
Average velocity =
Total time taken = 5s + 6s = 11s
The first distance covered = velocity x time = 1.4 x 5 = 7m
second distance covered = velocity x time = 1.4 x 6 = 8.4m
So;
Average velocity =
= 1.4m/s
Answer:
Maximum distance of image from mirror is equal to focal length of the mirror
Explanation:
As we know by the equation of mirror we have

here we know for convex mirror
object position is always negative as it will be placed behind the mirror always
while the focal length of the convex mirror is always taken positive
So here we have


so here maximum value of image distance is equal to focal length of the mirror
Explanation:
causes hallucinations
causes lung cancer eg cigarettes
causes bad breath
damages the nervous system eg cocaine
The normal force exerted on the rover when it rests on the surface of the planet be greater is 3,125.22 N.
<h3>
What is normal force?</h3>
A normal force is defined as the force that a surface exerts on an object.
N = W
N = mg
where;
- m is mass of the object
- g is acceleration due to gravity
Normal force is proportional to the weight of an object be considered.
<h3>Normal force of the rover</h3>
N = mg
N = 1,063 kg x 0.3(9.8 m/s²)
N = 3,125.22 N
Thus, the normal force exerted on the rover when it rests on the surface of the planet be greater is 3,125.22 N.
