A rocket with a mass of 2.0 Ã 106 kg is designed to take off from the surface of the earth by burning fuel and ejecting it with

julsineya [31]

thrust force getting from the burning of mass should balance the weight of the rocket

here thrust force is given as

$F_t = v\frac{dm}{dt}$

now by force balance we can say

$mg = v \frac{dm}{dt}$

now plug in all values in this

$(2 \times 10^6)(9.8) = 3500 \times \frac{dm}{dt}$

$\frac{dm}{dt} = \frac{19.6 \times 10^6}{3500}$

$\frac{dm}{dt} = 5600 kg/s$

so rate of mass burning per second will be 5600 kg per second in order to lift up the rocket

What is the difference between electromagnet and electromagnetism?

trapecia [35]

An electromagnet is a made coil associated with a ferromagnetic core. ... When an electric current flows through the wire the solenoid generates a magnetic field similar to that of a bar magnet. An electromagnet is a solenoid wound around a central iron core.

Electromagnetism is a process through which a material is magnetized (temporarily or permanently) by Electric current. ... This is Electromagnetism.
