Answer:

hey mate here is your answer

So if an object has a very small velocity (not moving very far over time, even though a large force may be applied to it, the Power will remain small. ... Stepping on the gas, or "speeding up" the car, is applying a force which will increase velocity and increase power.

The engine of a 2000 kg Mercedes going up Pike’s Peak delivers energy to its drive wheel at the rate 100 kW . Neglecting air res
kykrilka [37]

Answer:

v = 10 m/s

Explanation:

given,

Mass of Mercedes engine = 2000 Kg

Power delivered = 100 kW

angle made with horizontal = 30°

acceleration due to gravity =  10 m/s²

largest speed car can sustain = ?

we know,

Power = Force x velocity

P = F x v

P = mg sinθ x v

P = mg sin 30° x v

P = 0.5 mg  x v

v = \dfrac{100 \times 10^3}{0.5\times 2000 \times 10}

v = 10 m/s

hence, the maximum velocity is equal to v = 10 m/s

What is the mass of a 100-N crate of delicious candy
Svetach [21]

Answer:

Explanation:

weight ( w ) = 100 N

mass (m) = ?

WE know

g = 10 m/s²

w = m * g

or

m = w / g

m = 100 / 10

m = 10 kg

hope it will help :)

3x - 4 > 4x - 8 simplify​
Anit [1.1K]

Answer:

<em>x < 4</em>

Explanation:

<u>Inequalities</u>

The inequalities relate expressions using signs different from the equal sign, like "<" or "<" among others.

They can be treated as a normal equation but in case of directional relationals, care must be taken when multiplying or dividing by negative numbers.

The inequality given in the question is

3x - 4 > 4x - 8

Subtracting 3x in both sides

3x - 4 -3x > 4x - 8 -3x

Simplifying

-4 > x - 8

Adding 8

-4 + 8 > x - 8 + 8

Simplifying

4 > x

The solution comes by flipping both sides and the inequality sign

x < 4

How much electrical energy is used by a 75 W laptop that is operating for 12<br>minutes?​
Liono4ka [1.6K]

"1 watt" means 1 joule of energy per second.

75 W means 75 joules/sec .

Energy = (75 Joule/sec) x (12 min) x (60 sec/min)

Energy = (75 x 12 x 60) (Joule-<em>min-sec</em> / <em>sec-min</em>)

<em>Energy = 54,000 Joules</em>
