Answer:
1. As rocket mass increases, acceleration decreases.
2. The inverse of the mass of the boat.
Explanation:
1. Newton's second law of motion states;
F = ma
where F is the force applied, m is the mass and a is the acceleration.
Therefore, increasing the mass of a rocket increases its weight which would reduce its acceleration provided that the force is constant. Thus, as rocket mass increases, acceleration decreases.
2. The slope of the graph can be expressed as;
From Newton's second law,
F = ma
Slope = (Δa) ÷ (ΔF)
Slope = 
⇒ 
=
Therefore, the slope of the graph is the reciprocal of the mass of the boat.
Answer:
72 m/s
Explanation:
D1 = 3 cm, v1 = 2 m/s
D2 = 0.5 cm,
Let the velocity at narrow end be v2.
By use of equation of continuity
A1 v1 = A2 v2
3.14 × 3 × 3 × 2 = 3.14 × 0.5 ×0.5 × v2
v2 = 72 m/s
yes, just like human skin. The bigger you grown the more your skin stretches, I a fish is bigger their skin will stretch leading to broad stripes.
Since the choices are not given, I can't give an exact answer. Sublimation is the physical change occurring from solid to gas. This is very rare because the molecular arrangement of a solid and gas are opposite to each other. Thus, it depends on the properties of the substance. For example, napthalene could sublime at room temperature.

<h3>What is ABS?</h3>
ABS is known as an Anti-lock braking systems (ABS) that act in the capacity of steering one in times in emergencies by bringing back traction to one's tires.
Note that it often helps to hinder wheels from locking up and helping the driver to be able to steer to safety.
When vehicle wheels are about to lock, the ABS senses the impending lock up and prevents this from occurring is true as that is its function.
Note that Electronic stability helps to control helps to the risk of rollover crashes, such as are common with SUVs.
