Answer:
Explanation:
where;
= final velocity = 0
= initial velocity = 60 km/h = 16.67 m/s
= acceleration
= distance
First all of, because acceleration is given in m/s and not km/h, you need to convert 60km/h to m/s. Our conversion factors here are 1km = 1000m and 1h = 3600s
Solve for a;
Begin by subtracting
Divide by 2d
Now plug in your values:
If you're wondering why I calculated acceleration first is because in order to find force, we need 2 things: mass and acceleration.
m = mass = 900kg
a = acceleration = -2.78m/s
It's negative because the force has to be applied in the opposite direction that the car is moving.
Answer: its better to use parallel because, in parallel connection there will be more advantages than a series connection. and also the electronic devices are wired in series so thats why you should use parralel in house wiring
so its c.
because the parallel is wired through the whole house so if one of the circuits fail youŕe not screwed
Explanation:
A. Yes electricity is a fuel this is because protons are being displaced threw currents of electricity that are the used too charge a coil witch spins causing rotationional force And power too appropriate machine
B. Octane
C.one advantage is more power since octane is more combustable than electricity it makes gas or Diesel engines more powerful as too why there are no semi trucks being powered by electricity.
D. One disadvantage is effectively how well its fuel is spent gas is 69.78% less efficient
Answer:
Gravitational force will be 16 times more.
Explanation:
we know;
Gravitational force (F) = (Gm1m2)/d^2
when mass of each is doubled and distance between them is halved;
F= (G2m1×2m2)/(d/2)^2
=(4Gm1m2)/(d^2/4)
=4×4(Gm1m2)/d^2
=16(Gm1m2)/d^2
=16F
Answer:
The answer is (Base quantities or fundamental quantities) and (Derived quantities).
Explanation:
hope it helps.
