The acceleration due to gravity near the surface of the planet is 27.38 m/s².
<h3>
Acceleration due to gravity near the surface of the planet</h3>
g = GM/R²
where;
- G is universal gravitation constant
- M is mass of the planet
- R is radius of the planet
- g is acceleration due to gravity = ?
g = (6.626 x 10⁻¹¹ x 2.81 x 5.97 x 10²⁴) / (6371 x 10³)²
g = 27.38 m/s²
Thus, the acceleration due to gravity near the surface of the planet is 27.38 m/s².

Answer:
36 m³
Explanation:
From gas laws, at a constant temperature, the product of volume and pressure are directly proportional hence expressed as p1v1=p2v2 where p is pressure while v represent volume. Subscripts 1 and 2 represent the initial and respectively. Making v2 the subject then
Substituting 120 kpa for P1, 12m³ for V1 and 40 kpa for p2 then
Therefore, the volume will be 36 m³
The answer is 2.31!!!!!!!
Explanation :
There are many types of simple machines i.e. lever, wedge, pulley, wheel and axle etc.
Fulcrum is the pivot point about which the lever turns. When the position of the fulcrum is shifted, the position of effort changes.
There are three classes of the lever as class 1, class 2 and class 3.
Class 1 includes seesaws and scissors.
class 2 includes wheelbarrow
class 3 includes tongs and tweezers.
