The gas tank of a car is filled with a nozzle that discharges gasoline at a constant flow rate. Based on unit considerations of

mojhsa [17]

Answer:

$V=\dfrac{dV}{dt}.t$

Explanation:

Given that nozzle discharge at constant flow rate.

Volume of tank is V

Lets constant flow rate =Q

We know that

$Q=\dfrac{dV}{dt}\ L^3/s$

To find the time t,at a volume V

V = Q .t

$V=\dfrac{dV}{dt}.t$

Where t is the filling time of volume .

dV/dt is the volume floe rate .

Q is the discharge.

As a delivery truck travels along a level stretch of road with constant speed, most of the power developed by the engine is used

velikii [3]

Answer:

128 N

Explanation:

Power can be defined as

$P = F\cdot v$

<em>F</em> is the force and <em>v</em> is the velocity.

$F = \dfrac{P}{v}$

According to the question, <em>P</em> = 5.15 hp = 5.15 × 746 W.

<em>v</em> = 30 m/s

$F = \dfrac{5.15\times 746\text{ W}}{30\text{ m/s}} = 128 \text{ N}$

Since most of the power is used to compensate for the energy transformations due to friction forces, the total frictional is 128 N

Which part of an atom is gained, lost, or shared during a chemical reaction? Electron

siniylev [52]

Answer:

The gain,loss, or sharing of electrons occurs in every chemical bond.

Explanation:

Should electrons be lost by one particle, and gained by another particle, the now charged particles can be chemically bound by an ionic bond.

Should a pair of electrons form a region of high electron density between two positively charged atomic nuclei, a bond can occur in that mutual attraction of the positively charged nuclei towards the region of high electron density operates. This is a long-winded description of a covalent bond.

With the aid of a string, a gyroscope is accelerated from rest to 32 rad/s in 0.40 s. What is its angular acceleration in rad/s2

Irina-Kira [14]

<h2>Angular acceleration is 80 rad/s² </h2><h2>Number of revolutions undergone is 1.02</h2>

Explanation:

We have equation of motion v = u + at

Initial angular velocity, u = 0 rad/s

Final angular velocity, v = 32 rad/s

Time, t = 0.40 s

Substituting

v = u + at

32 = 0 + a x 0.40

a = 80 rad/s²

Angular acceleration is 80 rad/s²

We have equation of motion s = ut + 0.5 at²

Initial angular velocity, u = 0 rad/s

Angular acceleration, a = 80 rad/s²

Time, t = 0.4 s

Substituting

s = ut + 0.5 at²

s = 0 x 0.4 + 0.5 x 80 x 0.4²

s = 6.4 rad

Angular displacement = 6.4 rad

$\texttt{Number of revolutions = }\frac{6.4}{2\pi}=1.02$

Number of revolutions undergone is 1.02

A tennis ball is dropped from a height of 3 m and bounces back to a height of

julsineya [31]

Answer:

To decide where the balls land, we need to determine how long the balls are in the air. Both balls will take 2 seconds to hit the ground.

Explanation:

1) Time played forward : gravity & drag forces are in opposite directions so it takes a longer time to reach the ground. 2) Time played backward : gravity & drag forces are in the same direction so it takes a shorter time to reach the ground.
