Answer:
0N
Explanation:
Is the car is moving in a constant direction with constant speed, the composite force is null. We know what because any object that nonzero composite force is applied to will accelerate in the direction of the force, and this one doesn't.
In a parallel circuit, both bulbs are connected directly to the power supply
or battery. As long as the power supply is capable of running both of them,
neither bulb is aware of the other's presence. If one bulb fails 'open', the
other bulb doesn't change at all. The voltage across it, the current through it,
its resistance, and its brightness,all remain exactly as they were before.
change in velocity is 3m/s,the force exterted by bat on ball is 4.8N and the acceleration is 30m/s².
<h3>Give some difference between velocity and speed.</h3>
1) Speed is scalar quantity but velocity is vector quantity.
2) Speed is distance followed by an individual with respect to time and velocity is displacement with respect to time .
1) final velocity- intial velocity
25-22= 3m/s
2) The force is
F= ma
. 0.16×30= 4.8N

For an atom to achieve a stable electron configuration, it needs 8 valence electrons. Since this atom has 6 valence electrons, it needs 2 more to achieve a stable electron configuration.
8-6=2
A compound is combining two or more substances chemically and it’s pure with a new substance forming, a mixture is combing two or more substances into one physically its impure and no new substances form
