hjlf

Answer:

16.93545 m

Explanation:

m_1 = Mass of astronaut = 93 kg

m_2 = Mass of satellite = 1400 kg

v_1 = Velocity of astrounaut

v_2 = Velocity of satellite = 0.15 m/s

As linear momentum of the system is conserved

m_1v_1+m_2v_2=0\\\Rightarrow v_1=-\frac{m_2v_2}{m_1}\\\Rightarrow v_1=-\frac{1400\times 0.15}{93}\\\Rightarrow v_1=2.25806\ m/s

As there is no acceleration

Distance = Speed × Time

Distance=2.25806\times 7.5=16.93545\ m

The initial distance from the shuttle to the astronaut is 16.93545 m

Identify the method of thermal energy transfer.
Solnce55 [7]

Answer:

A: Conduction

B: Convection

C: Radiation

Explanation:

Conduction is the transfer of heat in internal energy by microscopic collisions of particles and movement of electrons within a body so from the fire hitting the metal. Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids so the water boiling in the pot. Radiation is the handle heating up due to the heat interacting with it.
