The force of gravity on a certain object is calculated through the equation,
F = Gm1m2 / r²
where F is the force, G is a constant, m1 and m2 are masses of the object and Earth, respectively and r is the distance. Substituting the known values for this item,
F = (6.67 x 10⁻¹¹ N.m²/kg²)(1 kg)(5.98 x 10²⁴ kg)/ (6.4 x 10⁶ m)²
F = 9.37 N
Answer: 9.37 N
Explanation:
Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium.
Answer:
because a complete equation must have all the elements present on the left hand side of the arrow on the right hand side of the arrow as well, and to be balanced there must be the same number of each type of atom, so both A and C are full equations, but A is not balanced because although there are two oxygen atoms on each side of the arrow, there is only one hydrogen atom on the left and two on the right, thus the right hand side is 'heavier' than the left and the equation is unbalanced.
Explanation:
a = Δv + xt^2 is not a kinematic equation.
<h3>What is a kinematic equation?</h3>
Kinematic equations are those equations that equations that could be used to describe the motion of a body without involving the force that makes the object to move. In considering the kinematic equations, we have to consider the following;
- Initial velocity
- Final velocity
- position
- acceleration
Thus, looking at the kinematic equations as shown, we can see that the equation; a = Δv + xt^2 is not a kinematic equation.

Answer: 10.67 m/s²
Explanation:
Given, l = 50 cm = 0.5 m
T = 2π √(L / g) , where
L = length of spring
g = acceleration due to gravity
T = period
T can also be gotten using the formula,
T = total number of oscillations / time taken, so that
T = 136 / 100
T = 1.36
T = 2π √(L / g)
1.36 = 2 * π * √(0.5 / g)
1.36 = 6.284 * √(0.5 / g)
1.36² = 6.284² * (0.5 / g)
1.85 = 39.49 * 0.5 / g
g = 19.745 / 1.85
g = 10.67 m/s²
Thus, we can infer that the value of g on this planet is 10.67 m/s²
