f = 280 Hz, l = 0.65 m, μ = 8x10^-4 kgm^-1Therefore use the equation f=(1/2l)(T/μ)^1/2Rearrange it to get it in the form T= by multiplying f by 2l, squaring both sides and then multiplying by μ to getT = ...

Specific question: The hot tub system has a volume of 4.5 m3 and is filled with water at a temperature of 28 °C. The heater transfers thermal energy to the water at a rate of 2.7 kW while a pump circulate...

First let’s split the problem into 2 parts: Vertical(y direction) and Horizontal(x direction.Vertical: u_y = 10 sin (30) = 5ms^-1
As for the ball to stop at max height and the fall down, all the kine...

ΔP = Δh ρ g
Δh = 1.7 - 0.5 = 1.2 m ρ = 1030 kg/m³g = 9.8 N/kg
ΔP = 1.2 (m) x 1030 (kg/m³) x 9.8 (N/kg)
= 12,112.8 N/m² = 12,112.8 Pa

Plot: I-V curve of an ideal resistor is a straight line with a positive gradient passing through (0,0)The I-V curve of an ideal resistor is a straight line because ideal resistors strictly obey Ohm's law ...
