Let height of twin falls = x
height of seven falls = 2.5x

x + 2.5x = 420
3.5x = 420
x = 420/3.5 = 120

so twin falls = x = 120 ft
seven falls = 2.5x = 300 ft

A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exerts a force of 1250 pou
Ierofanga [76]

Answer:

Option d is correct.

The magnitude of the resultant force upon the piling = 2930 lbs.

Explanation:

Resultant of a group of forces = vector sum of the forces.

Force 1 = (-1250î) lbs

Force 2 = (2650j) lbs

Resultant = (-1250î + 2650j) lbs

The magnitude of the resultant = √[(-1250)² + (2650)²] = 2930 lbs.

Or in visualization method, the two forces presented form a right angled triangle with the resultant of the two forces.

Hence, using Pythagoras theorem,

F₁² + F₂² = R²

(1250)² + (2650)² = R²

R = √[(1250)² + (2650)²] = 2930 lbs.

A future space explorer has been kidnapped and is held prisoner on a planet in our solar system. With nothing else to do, our pr
DIA [1.3K]

To develop this problem we will apply the linear motion kinematic equations. Specifically, the second law that describes the position of a body as a function of its initial velocity, time and acceleration.

y = ut+\frac{1}{2}gt^2

Here,

u = Initial velocity

t = Time

g = Acceleration due to gravitation

If we replace the values to find the gravitational acceleration we have then,

1.7m = 0+\frac{1}{2} g*0.36^2

g= 26.2346m/s^2

Recall that the force of gravity on the planet Jupiter is 24.79 m / s² so the measure is closer to this planet. It is likely that you are in Jupiter.

A dogsled team has a total momentum of 1710 kg•m/s. If the team has a total mass of 450 kg, what is its speed?
HACTEHA [7]

Answer:

3.8 m/s

Explanation:

Momentum is the product of mass and velocity hence

Momentum=mv where m is mass and v is the velocity of an object

Making v the subject of the formula then

v=\frac {momentum}{m}

Substituting 1710 kgm/s for momentum and 450 Kg for mass we obtain

v=\frac {1710 Kgm/s}{450 Kg}=3.8 m/s

Hence the speed of dogsled team is 3.8 m/s

A wave transfers _______ as it moves away from the source.
stiks02 [169]

Answer:

A wave transfers energy as it moves away from the source.

Explanation:

A wave transfers energy as it moves away from the source. A wave is known to be a disturbance that travels through a medium and transfer energy from a point to the other without causing any permanent displacement of the medium itself.

Let's take water as an example of a medium through which wave is transfered. As the water moves away from its source, the wave generates energy. The wave produces a motion which leads to transfer of kinetic energy as the medium moves from its source since kinetic energy is the energy acquired by a body by virtue of its motion.
