Answer:
-35
Explanation:
<u>Deceleration is the complete opposite of acceleration and is calculated by adding a negative sign to the formula for finding acceleration.</u>
Since acceleration is calculated by diving the change in velocity with time, deceleration will become:
Deceleration = -Δv/t, where Δv = change in velocity and t = time
In this case, Δv = 70 m/s and t = 2 s, hence;
Deceleration = -70/2 = -35
<em>The deceleration is 35 </em><em>.</em>
Answer:
The equivalent resistance of the combination is 3.42 ohms.
Explanation:
We have,
8 ohms resistor is connected in parallel with a 6 ohms resistor. It is required to find the equivalent resistance of this combination.
For a parallel combination, the equivalent resistance is given by :
Plugging the values of R₁ and R₂, we get :
So, the equivalent resistance of the combination is 3.42 ohms.
Answer:
(a). 12 plants
(b). 3171 $
Explanation:
(a)first convert units of 100 billion kWh/year into Watts(W)
also convert the units of 1000 MW into Watts(W)
1 billion = 10^9
1 year = 365*24 = 8760 hrs
so
100 billion kWh/year = 1
= W
1000 MW =
no. of plants = = 11.4
So 12 plants required
(b)
savings = unit price*total units
=
= 3170.9 =3171 $
