We will start by defining the units and their respective equivalences between the proposed measurement systems
PART A ) The mileage of the car is 55mpg (Miles per gallon)
Therefore the mileage of the car is 23.4km/L
PART B ) The mileage of the car means that the car travels 23.4km and consumes 1 liter of fuel. Then
For the car to travel 1500km the amount of fuel would be,
But 1 gas tank can only hold 45Liters of fuel, then the number of tank required would be
Thus the number of tanks of gas required to drive 1500km is 1.4
Answer:
F = 100 N
Explanation:
The torque is given by the expression
τ = F x r
where bold letters indicate vectors, the magnitude of this expression is
τ = F r sin θ
In general, when tightening a nut, the force is applied perpendicular to the arm, therefore θ = 90 and sin 90 = 1
τ = F r
F = τ / r
calculate
F = 30 / 0.30
F = 100 N
Answer:
It’s b
Explanation:
Everyone else is wrong and I tried this and got it right
Answer:
9.45 kWh
Explanation:
Energy = Power × time
E = 900 W × (1.5 h/day × 7 day)
E = 9450 Wh
E = 9.45 kWh
