A change in either speed or direction results in... Because velocity includes direction, it is possible for two objects to have the same speed but different velocities. <span>A change in Velocity

Not really sure want the answer is but this is all i can think of :/

The word "changes" goes in the blank. Another name for any of these changes is "acceleration".

In an eslastic ,the momentum is_______and the mechanical energy is​
DIA [1.3K]

Answer:

In an elastic collision, the momentum is conserved and the mechanical energy is conserved too.

Explanation:

There are two types of collisions:

- Elastic collision: in an elastic collision, the total momentum before and after the collision is conserved; also, the total mechanical energy before and after the collision is conserved.

- Inelastic collision: in an inelastic collision, the total momentum before and after the colllision is conserved, while the total mechanical energy is not conserved (in fact, part of the energy is converted into other forms of energy such that thermal energy, due to the presence of frictional forces)

A raft is made of 10 logs lashed together. Each is 56cm in diameter and has a length of 6.1m. How many people can the raft hold
astra-53 [7]

Answer:

n = 87 the number of people can raft hold

Explanation:

The raft is made of 10 logs

No given the information to find the average person assuming

w = 69 kg , wₙ = 0.60

e = 56 cm * 1 / 100 cm = 0.56 m

l = 6.1 m

V = 10 * 6.1m * (0.56m /2) ² π

V = 15.024 m³

m₁ = V * L³ * wₙ + mₙ

m₂ = V * L³

m₁ < m₂

n < V * (1 - wₙ) * L₃ / w

n < 15.024 m³ * ( 1 - 0.60) * 10³ / 69 kg

n ≅ 87

Is the number of maximum people

An important news announcement is transmitted by radio waves to people sitting next to their radios 42 km from the station and b
Alik [6]

Answer:

news will reach to the listener who are 42 km apart

Explanation:

given,

distance of the radios from the station = 42 Km

speed of the sound in the air = 343 m/s

distance of the people = 9.26 m

time =\dfrac{distance}{speed}

time taken by the signal to reach to the radio

speed of the electromagnetic wave to reach to the people

speed of electromagnetic wave = 3 × 10⁸ m/s

t =\dfrac{42000}{3 \times 10^8}

t = 1.4 μs

time taken to reach to the people

time =\dfrac{distance}{speed}

t =\dfrac{9.26}{343}

t = 27 ms

time taken by the station to radio is less.

hence, news will reach to the listener who are 42 km apart

A small aircraft, on a heading of 225°, is cruising at 150 km/h. It is encountering a wind blowing from a bearing of 315° at 35
ki77a [65]

As we can see in the figure attached here

The velocity of aircraft is given as

v_p = 150 km/h at 225 degree

velocity of wind is given as

v_a = 35 km/h at 315 degree

so here the net velocity of aircraft will be the vector sum of aircraft speed and wind speed

since in the figure we can see that the two speeds are perpendicular to each other

so we can say that the resultant of two speed can be given by using Pythagoras theorem

so we will have

v_{net} = \sqrt{v_a^2 + v_p^2}

v_{net} = \sqrt{150^2 + 35^2}

v_{net} = 154 km/h

so net speed of aircraft will be 154 km/h
