Answer:

Distance, d is 86.1 meters.

Explanation:

Given the following data;

Time, t = 6.15secs

Velocity = 14m/s

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

Velocity = \frac{distance}{time}

V = \frac{d}{t}

d = Vt

Substituting into the above equation;

d = 14 * 6.15

d = 86.1m

Hence, the distance traveled by the boat is 86.1 meters.

Find the frequency (in hertz) of the first overtone for a 1.75 m pipe that is closed at only one end. Use 350 m/s for the speed
serg [7]

Answer:

The first overtone frequency is 100 Hz.

Solution:

According to the question:

Length of pipe, l = 1.75 m

Speed of sound in air, v_{sa} = 350 m/s

Frequency of first overtone, f_{1} is given by:

f_{1} = \frac{v_{sa}}{2l}

f_{1} = \frac{350}{2\times 1.75} = 100 Hz

Since, the frequency, as clear from the formula depends only on the speed

and the length. It is independent of the air temperature.

Thus there will be no effect of air temperature on the frequency.

Your job is to lift 30 kgkg crates a vertical distance of 0.90 mm from the ground onto the bed of a truck. For related problem-s
Gekata [30.6K]

Answer:

The number of crates is 84580.

Explanation:

mass, m = 30 kg

height, h = 0.9 mm  

Power, P = 0.5 hp = 0.5 x 746 W = 373 W

time, t = 1 minute = 60 s

Let the number of crates is n.

Power is given by the rate of doing work.

P = \frac{n m gh}{t}\\\373 =\frac{n\times 30\times9.8\times 0.9\times 10^{-3}}{60}\\\\n =84580

Two identical trucks, having the same mass, are traveling down a long straight flat road at constant speeds. However, Truck A ha
denis-greek [22]

Answer:

Momentum

Explanation:

Truck A has a greater momentum compared to Truck B.

Momentum is the product of mass and velocity of a body;

     Momentum = mass x velocity

We see that the body with more mass and velocity will have a higher momentum.

Since the two bodies have the same mass, and the speed A is greater, then A will have a greater momentum.
