Answer:
52 N
Explanation:
Given:
Work done= 1820 J, distance= 35 meters Force = ?
Formula for work done
W = F • d
Find F.
F = W / d
Substitute the given into the equation.
F = 1820 J / 35 m
= 52 N
Answer: parasitic organisms cause harm to other organisms.
Answer:
40.34 s
Explanation:
Given,
Velocity (v) = 5.33 m/s
Distance (s) = 215 m
Time (t) = ?
We know that,
Speed (v) = distance (s)/time (t)
⇒ time(t) = distance (s)/speed (v)
= 215/5.33 = 40.34 sec
∴ time(t) = 40.34 sec.
Answer:
Explanation:
When loading muzzle-loading firearm it is important to eliminate any air space between the projectile and the powder charge because it may create dangerous pressure build inside the muzzle.
The high amount of Pressure build-up may backfire the bullet and may cause harm to the fireman. It creates a high magnitude impulse on the fireman which can be dangerous for his body parts. High pressure may also explode the gun powder on the spot and causes a fire.
Because of friction and air resistance, every moving object will eventually come to rest unless a continuous net force is applied to it.
<h3>What is friction?</h3>
Friction is the opposition offered to motion of a body over another body.
Friction can either be:
- Solid friction as in friction in solids
- Fluid friction as in air resistance
The law of inertia states that an object will remain in its state of rest or state of motion in a straight line unless acted upon by an external force.
However, due to friction and air resistance, every moving object will eventually come to rest unless a continuous net force is applied to it.
In conclusion, moving objects come to rest because of friction and air resistance.
