A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and m

coldgirl [10]

Answer:

Answer:

f) The puck conserves its original momentum but loses some, but not all, of its mechanical energy.

Explanation:

It is a case of perfectly inelastic collision . So momentum will be conserved because no external force acts on them during the collision . But there will be loss of energy ( kinetic energy ) . It will be in the form of sound or heat that is produced during collision. They will still have some kinetic energy even after the collision.

A boat of mass 250 kg is coasting, with its engine in neutral, through the water at speed 1.00 m/s when it starts to rain with i

bija089 [108]

Answer:

$v_o\approx0.7059\ m.s^{-1}$

Explanation:

Given:

mass of the boat, $m=120\ kg$

uniform speed of the boat, $v=1\ m.s^{-1}$

rate of accumulation of water mass in the boat, $\dot m=100\ kg.hr^{-1}$

time of observation, $t=0.5\ hr$

The mass of the boat after the observed time:

$m_o=m+\dot m\times t$

$m_o=120+100\times 0.5$

$m_o=170\ kg$

Now using the conservation of momentum:

$m.v=m_o.v_o$

$120\times 1=170\times v_o$

$v_o\approx0.7059\ m.s^{-1}$

At take off, a plane flies 100 km north before turning to fly 200 km east. How far is its destination from where the plane took

IRINA_888 [86]

Answer

224 Km

4 Km

Explanation

Part 1

The plane flies 100 Km north and then 200 Km east. This makes a 90° turn. To get the distance taken by the plane we get the hypotenuse.

c² = a² + b²

c² = 100² + 200²

= 50,000

c = √50,000

= 223.606 Km

The answer to the nearest whole number is 224 Km

Part 2

If the runner run 15 Km north then 11 Km south, the resultant distance would be,

15 - 11 = 4 Km

The speed of sound I gases depends on a humidity b air c temperature d visibility

Mazyrski [523]

The speed of sound in gases is represented mathematically as:

v(sound) = √γRT/M

where γ = adiabatic constant which is the ratio of the heat capacities at constant pressure and constant volume; Cp/Cv

R = gas constant

T = temperature

M = molar mass of the gas

Hence, the speed of sound in gas is directly proportional to the square root of temperature.

Ans: c) temperature
