Mercury does not wet glass because of the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.
<span>The only thing that can change the motion of an object is a net (unbalanced)</span>force acting on it. This is given by Newton's First Law of Motion, sometimes <span>also called the Law of Inertia.
I hope this helps!</span>
No, non-moving objects do not have inertia.
Answer:
170 N
Explanation:
The following data were obtained from the question:
Mass (m) = 20 Kg
Angle (θ) = 30°
Acceleration due to gravity (g) = 9.8 m/s²
Weight (W) =?
The perpendicular component of the weight can be obtained by using the following formula:
W = mg × Cosθ
W = 20 × 9.8 × Cos 30
W = 196 × 0.866
W = 169.7 ≈ 170 N
Therefore, perpendicular component of the weight is 170 N
52.1-4.184=47.916 You then either add or subtract this from 68.6 the first temperature of the metal. This will give you your total.
