Answer:

d=11\sqrt2\ km

Explanation:

Given that,

Displacement in North = 11 km

Displacement in East = 11 km

We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :

d=\sqrt{11^2+11^2}\\\\= 11\sqrt2\ km

Hence, the approximate displacement of the hiker from the camp is 11\sqrt2\ km.

At the end of the movie Titanic, Rose lies on a piece of furniture, floating in the ocean, and Jack drowns. A common objection p
julsineya [31]

Answer:

If jack is in the piece of furniture it would submerge.

Explanation:

The piece of furniture would submerge if the  weight applied on the furniture is greater than the maximum buoancy force the water can provide.

maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.

                                       = 1025\times v\times 9.8

v = area × thickness of pine

  1.5\times 5\times 10^{-2}

 = 0.075 m^{3}

therefore buoancy force = 1025×0.075×9.8 N

                                         = 753.375 N

weight of rose alone = 46×9.8 N = 450.8 N

weight of jack alone = 58×9.8 = 568.4 N

weight of pine = density of pine × volume of pine

                        = 350 × 0.075= 26.25 N

weight of pine + weight of rose = 450.8+26.25=477.05 N

weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N

therefore if jack is in the piece of furniture it would submerge.

Kiley went 5.7 km/h north and then went 5.8 km/h west. From start to finish, she went 8.1 km/h northwest.
avanturin [10]
5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.<span>

The answer choice above is correct.

The instantaneous velocities are the actual </span>velocities while traveling ( the velocity during that instant ). The average velocity is the average of the instantaneous velocities ( the speed in one direction equivalent to the two speeds <span>in different directions ).

I used speed in the explanation because velocity is speed with direction.</span>

A bumper car with a mass of 200 kilograms traveling at a velocity of 3.5 meters/second collides with a stationary bumper car wit
Ainat [17]
Answer: fourth option 1.2 × 10³ joules

Explanation:

1) kinetic energy is calculated as the half of the product of the mass times the square of the speed:

=> KE = (1/2) m × (v)²

2) you know the mass after the collision and the speed so you have all the data fo find the numerical value of the expression for KE:

m = m1 + m2 = 200 kg + 250 kg = 450 kg

KE = (1/2) × 450 kg × (2.3 m/s)²  = 1,190.25 joules ≈ 1200 joules = 1.2 × 10³ joules, which is the last option of the list.

The power produced by an electric motor is 400w.how long will it take the motor to do 10,000 j of work
Lubov Fominskaja [6]

Answer:

Energy = Power × Time

We make Time the subject in this equation

Time = Energy ÷ Power

Time = 10000 ÷ 400

Time = 25seconds
