Answer:

<h2>2.00 N/kg approximately.</h2>

Explanation:

A gravitational flied is defined as the quotient between the gravitational force and the mass:

g=\frac{F}{m}

Replacing all given values, we have:

g=\frac{175N}{97.6kg}\\ g=1.96\frac{m}{s^{2} }

Therefore, the gravitational filed is approximately 2.00 N/kg.

Constant velocity means the netto force = 0, therefore F(gravity) = F(astronaut).
175N divided by 87,5kg = 2.00kg/N

A Carnot engine whose high-temperature reservoir is at 620 k takes in 550 J of heat at this temperature in each cycle and gives
yarga [219]

Answer:

(a) W=217 J

(b) Tc=378K

(c) e=0.39=39%

Explanation:

For part (a)

We to calculate the mechanical work W the engine  does. By knowing QC and QH can obtain the work using equation  

W = IQHI — IQcl  .....................eq(1)

Put given values for QH and QC into equation (1) to get  

the mechanical work of the engine  

W = 550 - 335  

W=217 J

For part (b)

We want to determine the temperature of low temperature  reservoir which means Tc  

IQc|/|Qh| =TC/TH  

for Tc  

Tc=(IQc|/|Qh|)*TH

Now we can put values

Tc= 620K  (335/ 550.1)  

Tc=378K  

For part (c)

Here we want to find the thermal efficiency (e) of the cycle

e=1-TC/TH

e=1-(378/620)

e=0.39=39%

Why does nuclear fusion hold promise as an energy source ?
Andreyy89
Because it generates high amounts of energy for a small amount of material, and doesn't produce as much pollution as fossil fuels.

What is the difference between acceleration and linear acceleration?
Akimi4 [234]

Explanation:

Linear acceleration is a type of acceleration of a body along a straight path or line.

Acceleration is defined as the rate of change of velocity with time.

  Acceleration = \frac{Change in velocity}{time}

There are different types of acceleration .

  • linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
  • centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
  • Angular acceleration is the rate of change of angular velocity.
