What gauge pressure must a pump produce in order to pump water from the bottom of

Grand Canyon (730 m elevation) in Pascals and in atmosphere?

A bus starts its journey from the terminal and moves with constant velocity 25 ms^-1. When reaching the junction of a road, the driver steps on the brake pedal and the bus stops after travelling a distance of 50 m. Calculate the deceleration of the bus after the brake is applied.

A car with mass 1 500 kg moves with costant velocity of 36 ms^-1. The driver sees a group of cows in front and he immediately steps on the brake pedal and manages to stop the car in 6 seconds. The distance of the cows from the car when the driver spotted them was 160 m. How far are the cows from the car when the car stops.

A homogeneous wood cylinder of height h and density

p = 950 kg/m^3 when immersed in a liquid floats so that the emerging part is equal to 3⁄4 h. Calculate the density of the liquid.

A traveling wave on a taut string with a tension force T is given by the wave function: y(x,t) = 0.1sin⁡(2πx-300t), where x and y are in meters and t is in seconds. The linear mass density of the string is μ = 10 g/m, and the string is 10 m-long. The total energy on the string is

A 2.4 mol of ideal gas through an isochoric process in which the process in which the pressure changes from 1.8 atm to 2.9 atm at 200k. The specific heat of a gas at constant volume is 12.47j/mol.k . What was the initial temperature and the internal energy of the system?

A flight controller at an airport observes two aircrafts A and B simultaneously, their position vector being respectively (10i + 20j + 5k)km and (-20i - 10j + 3k)km relative to the control tower. A, flying with a constant velocity of (-40i - 50j)km/h and B, with a constant velocity of (150i + 250j + 60k)km/h.

Find

(i). The velocity of A relative to B

(ii) The position of A relative to B, t minutes after the aircraft are observed.

(iii) The value of t, correct to the nearest 10s, when A and b are nearest to each other.

I will be anticipating on an answer, thank you!

Lightwaves travel from the air into a lens made of glass. Their velocity decreases as they enter the glass. How does this affect the frequency and wavelength of the lightwaves?

Forces F₁ (east) and F₂ are simultaneously applied to a 3.0 Kg mass. When F₂ is east, a = 5.0m/s² east and when F₂ is west a = 1.0m/s² east. Determine the magnitude of F₁ and F₂.
