Answer:
a. 150 N
Explanation:
Gravitational Force: This is the force that act on a body under gravity.
The gravitational force always attract every object on or near the earth's surface. The earth therefore, exerts an attractive force on every object on or near it.
The S.I unit of gravitational force is Newton(N).
Mathematically, gravitational force of attraction is expressed as
(i) F = GmM/r² ........................ Equation 1 ( when it involves two object of different masses on the earth)
(ii) F = mg ............................... Equation 2 ( when it involves one mass and the gravitational field).
Given: m = 17 kg, g = 8.8 m/s²
Substituting into equation 2,
F = 17(8.8)
F = 149.6 N
F ≈ 150 N.
Thus the gravitational force = 150 N
The correct option is a. 150 N
An object is moving along a straight line and the uncertainty in its position is 0.1 m.
(a) Find the minimum uncertainty in the momentum of the object.
kg · m/s
(b) Find the minimum uncertainty in the object's velocity, assuming that the object is a golf ball (mass = 0.045 kg).
m/s
(c) Find the minimum uncertainty in the object's velocity, assuming that the object is an electron.
m/s
The number of pascal equivalent to 1 inch of mercury is 3386.53 pascal
From the question given above, we were told that:
29.92 inches of mercury = 1 atm
101325 pascal = 1 atm
Thus,
29.92 inches of mercury = 101325 pascal
- With the above information, we can obtain the number of pascal equivalent to 1 inch of mercury. This can be obtained as follow:
29.92 inches of mercury = 101325 pascal
Therefore,
1 inches of mercury = 101325 / 29.92
<h3>1 inches of mercury = 3386.53 pascal</h3>
Thus, the number of pascal equivalent to 1 inch of mercury is 3386.53 pascal
