A swimmer can travel 2.30 m/s in still water. The swimmer heads directly west across a steam whose current is 1.20 m/s n. What is his velocity relative to the ground

Answers

Answer:

velocity relative to the ground = 2.54 m/s

Explanation:

given data

still water Vx = 2.30 m/s

across a steam Vy = 1.20 m/s

solution

we get here first velocity relative to the ground is express as

velocity = $√(Vx^2+Vy^2)$ ...............1

put here value and we get

velocity = $√(2.3^2+1.20^2)$

velocity = 2.54 m/s

an object with a mass of 70 kilograms is supported at a height 8 meters above the ground . whats the potential energy of the object with respect to the ground?....A...560 J ...B... 3,430 J...C...5,488.... D...2,058 J

Answers

As per the question the mass of the object is given as 70 kg.

The height of the object from ground is 8 m.

We are asked to calculate the potential energy of that object.

The potential energy of a object is the energy gained by the body due to its position or configuration. The energy due to the position of object from the surface is called gravitational potential energy .

If a body of mass m is at a height of h from the ground,then its potential energy is calculated as -

potential energy $[P.E]= mgh$

where g is the acceleration due to gravity.

we have been given h= 8 m and m= 70 kg

we know that acceleration due to gravity g =9. 8 m/s^2

⇒ $P.E =70 kg *9.8 m/s^2*8 m$

=5488 Joule

Here Joule is the unit of energy.

using the formula E = m* g*h the answer is C...5,488 J. BTW m is mass g is gravitational pull ( 9.8 )and h is height above ground

Answers

Justin ! Justin ! ! You're in high school Physics. You've done Newton's Laws until you saw them in your sleep. When the wind rustles through the trees, you almost hear it whispering to you "F = M A". Now is the time to use that ! M=65kg. A=0.3m/s^2. F = (65)(0.3)=19.5 newtons.

400J of heat is produced in 4 sec in 4ohm resistor.calculate yhe PD across the resistor.

Answers

Actually, after the information you gave, I expected you to ask for the voltage
across the resistor, so I'm not quite sure what you mean by 'PD'. It could be the
"Potential Difference" or the "Power Dissipation" across the resistor.
Here are both answers:

Power Dissipation:
Power = Energy/time = 400 joules / 4 seconds = 100 joules/second = 100 watts.

Potential Difference (voltage):
Power dissipated by a resistor = (voltage)² / Resistance

100 watts = (voltage)² / 4 ohms

Multiply each side by 4 ohms:

400 watts-ohms = (voltage)²

Voltage = square root of 400 watts-ohms = 20 volts
