The answer would be radiation. Heat lamps give off IR radiation in order to heat the surroundings. No idea what you mean by "potential" in reference to heat transfer.
The slope of the road can be given as the ratio of the change in vertical
distance per unit change in horizontal distance.
- The maximum steepness of the slope where the truck can be parked without tipping over is approximately <u>54.55 %</u>.
Reasons:
Width of the truck = 2.4 meters
Height of the truck = 4.0 meters
Height of the center of gravity = 2.2 meters
Required:
The allowable steepness of the slope the truck can be parked without tipping over.
Solution:
Let, <em>C</em> represent the Center of Gravity, CG
At the tipping point, the angle of elevation of the slope = θ
Where;
The steepness of the slope is therefore;
Where;
= Half the width of the truck = 
= 1.2 m
= The elevation of the center of gravity above the ground = 2.2 m
The maximum steepness of the slope where the truck can be parked is <u>54.55 %</u>.

Answer:
That is true.
Explanation:
When the input force is applied to the wheel, as it is with a doorknob, the axle turns over a shorter distance but with greater force, so the mechanical advantage is greater than 1.
Answer: 2960N
Explanation:
According to newtons first law of motion, force = mass × acceleration
To get acceleration,
Acceleration = velocity/time
Velocity = 80km/hr
Converting the velocity to m/s
80×1000/1×3600
velocity = 22.2m/s
Time = 9secs
Acceleration=22.2/9
Acceleration = 2.47m/s²
The get the force
F= 1200×2.47
F = 2960N
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest. ...
if α = 45°, then the equation may be written as: ...
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
