Answer:
Number 6:
• From the formula of force:
• But we need to get the acceleration, from the first newtons equation of motion
• v is the final velocity, but v is zero because the bullet came to rest.
• u is the initial velocity, u = 350 m/s
• a is the acceleration that we need
• t is the time, t = 0.0018 seconds.
» let's now substitute:
[ negative shows retârdation or deceleration or decrease in speed ]
• Therefore, let's find the force:
mass = 6g = (6/1000) kg = 0.006 kg
Answer:
There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
Explanation:
Answer:
0.50
Explanation:
The maximum height is given by here h is the maximum height u is the initial velocity and is the angle of projection
So we can see from the relation that height is universally proportional to the gravity now in question it is given that the planet has the twice the surface gravity than the earth so the height will be half
The order for the scientific method is
1. Ask a question
2. Form a hypothesis as an if, then statement (If the liquid is blue, then it must be water)
3. Conduct an experiment
4. Collect the observations
5. Analyze the data
6. Draw a conclusion using while restarting your hypothesis
