Two arrows are fired horizontally with the same speed of

Fed [463]

Answer:

Explanation:

Given

mass of each arrow=0.1 kg

velocity of arrow=30 m/s

One arrow is fired u=due to east and another towards south

Momentum of first arrow

$P_1=0.1\left ( 30\hat{i}\right )=3\hat{i}$

$P_2=0.1\left ( -30\hat{j}\right )=-3\hat{j}$

Total momentum P

$P=P_1+P_2$

$P=3\hat{i}-3\hat{j}$

magnitude $|P|=\sqrt{3^2+3^2}=3\sqrt{2}$

direction

$tan\theta =\frac{-3}{3}$

$\theta =45^{\circ}$ clockwise w.r.t to east

a fixed mass of gas occupies a volume of 1000 CM3 at 0 degree celsius if it is heated at constant pressure of 100 degree celsius

evablogger [386]

Answer:

P V = N R T ideal gas equation

V1 = k * T1 if P is constant and also N and R will be constant

V2 = k * T2 where k is some constant

Or V2 = (T2 / T1) * V1 also known as "Charles Law" for expansion at

constant pressure

V2 = (373 / 273) * 1000 cm^3 = 1366 cm^3 where T is absolute temperature

What represents a case in which you are not accelerating?

KIM [24]

Answer: dv/dt = 0

Explanation: Acceleration has to do with when you are changing velocity. since velocity is a speed and a direction you only accelerate when you change speed or change direction or change both in other words you are not accelerating when you are moving in a constant speed and at a specified direction. E.g driving Eastward at a constant speed of 24m/s, such scenario is a case of not accelerating that is acceleration is zero.

Furkat [3]

<span> Using conservation of energy

Potential Energy (Before) = Kinetic Energy (After)

mgh = 0.5mv^2

divide both sides by m

gh = 0.5v^2

h = (0.5V^2)/g

h = (0.5*2.2^2)/9.81

h = 0.25m

lawyer [7]

Answer:

Time taken, t = 30.15 minutes

Explanation:

It is given that,

Distance from the center of planet, r = 40 miles

Speed of the shuttle, v = 500 miles per hour

Let t is the time taken by it to complete one full orbit. The displacement of the shuttle is,
