state Newton's second law of
motion and write down
three examples to
justity it.
Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
[tex]f = m \times a[/tex]
f= force
m=mass
a=acceleration

Explain Newton's 2nd Law of Gravity in your own words ?
Answer:
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
8. What are elastic and inelastic collisions?
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.
An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else.

Lena is playing with a remote-controlled car in her backyard. She knows that the car uses a wheel and axle to move. What is the primary source of power for the wheel and axle in the remote-controlled car?
A.
friction between the ground and the tires
B.
radio waves from the remote control
C.
chemical energy from the batteries
D.
potential energy with the car sitting at the top of a small hill
The primary source of power for the wheel and axle in a remote-controlled car would be:
- Chemical energy from the batteries.
Chemical Energy
The key source that offers power to the wheel, as well as, the axle in the remote-controlled car would be 'the chemical energy that is released from the batteries.'These chemical energies would allow the car to function on the commands given by the remote. Thus, 'chemical energy' is the correct answer.Learn more about "Wheel and Axle" here:

A car is travel with velocity of 150 km/hr east. It traveled a distance of 500 km. How long did it travel for.
Explanation:
V= s / t
150 km/hr = 500 km / t
t = 500 km ÷ 150 km/hr
t = 10/3 hr (3 hrs 19 mins 49 sec)?
I'm not sure tho^^
Answer:
[tex]\boxed {\tt \frac{10}{3} \ hours}[/tex]
Explanation:
Time can be found by dividing the distance by the velocity. Use the following formula:
[tex]t=\frac{d}{v}[/tex]
The distance traveled was 500 kilometers. The velocity is 150 kilometers per hour.
[tex]d= 500 \ km \\v= 150 \ km/hr[/tex]
[tex]t=\frac{500 \ km} {150 \ km/hr}[/tex]
Divide. Note that the kilometers, or km, will cancel each other out.
[tex]t=\frac{500 \ }{150 \ hr}[/tex]
[tex]t=\frac{10}{3} \ hr[/tex]
[tex]t=3.3333333 \ hr[/tex]
The car traveled for 10/3 or 3.3333 hours
a jogger runs a distance of 100m and accomplished his feat in 30secs . What was his speed?
Answer:
His speed was 3.3
Explanation:
To find his speed all you have to do is to divide his distance ÷ time. Since your solving for speed all you do is divide distance ÷ time to find out your speed.

An airport has runways only 145 m long. A small plane must reach a ground speed of 44 m/s before it can become airborne. What average acceleration must the plane’s engines provide if it is to take off safely from its airport?
Answer:
The value is [tex]a = 6.676 \ m/s^2[/tex]
Explanation:
From the question we are told that
The length of the runways is [tex]l =145 \ m[/tex]
The required ground of a small plane is [tex]v = 44 \ m/s[/tex]
Generally from kinematics equation
[tex]v^2 = u^2 + 2as[/tex]
Here u is the initial speed of the plane which is 0 m/s
so
[tex]44^2 = 0^2 + 2 * a* 145[/tex]
=> [tex]a = 6.676 \ m/s^2[/tex]
find the weight of the following mass;
(a) 220g
please show the formula
Explanation:
weight=mass*gravity
w=mg
first change 220g to kg like this
1kg=1000g
?=220g
1kg*220g/1000kg=220/1000g
mass =0.22kg
now we can continue
w=0.22kg*10m/s^2 or w=0.22kg*10N/kg
=2.2N =2.2N
