Answer: yes it can be prevented
Explanation:
The sensation of weightlessness that astronauts experience seems to make their tasks almost effortless. However, as Newton's third law of motion suggests, working in space can be physically demanding.
As he tightens the bolt, he is rotating in the direction opposite to the bolt
It is possible if the handhold is designed in three dimensional motion where the astronaut motion will be the uplimb motion with the mass centre of hand move along circular helix trajectory
Angular momentum is conserved astronaut motion is conserved when net external torque is Zero.
Answer:
Meaning to bring ssomething to an end
Explanation:
For example if someone is wrapping up an essay a common phrase used is "In conclusion" (conclude beinf that base word) when restating their arguement.
Answer: The cake would be 100F after about 47 minutes
Explanation:
Initial temperature = 210F
Time at 140F = 30 minutes
At 140F the cake has lost (210-140)F
= 70F
70F is lost on 30minutes
Rate of temperature reduction
= (70/30) F/min
= 7/3F/min
To lose 110F from 210 to 100F
Temp/time = 7/3
110/t = 7/3
Cross multiply
t = 330/7
t = 47.1429minutes ~ 47min
Add all the resistances across the circuit together the calculate the total resistance
Answer:
They can do this with the help of mechanical power generated from the human muscle.
Explanation:
Since rescue workers engage in missions where it is usually difficult for them to get electrical energy to their devices and working tools, they could employ various materials that can be sourced around them to get energy to their tools. One of such is the mechanical power generated from the human body through squeezing and compressing.
Some green devices such as the dyno torch have been designed to be powered through this method. Repeated squeezing of its flywheel allows light to be generated.
