What’s Brainlyest? Can you post a picture of the question or farther explain what (m>s) means?
Answer:
convection
Explanation:
The only way convection can only take place in liquids and gas.Since the marshmello is neither,convection is the least effective way
Answer:
The mass of the astronaut is approximately 119.74 kg
Explanation:
Assuming this problem as a Simple Harmonic Motion of a mass-spring system, the period (T) of the oscillations for a mass (m) and spring constant (k) is:
(1)
First, we have to calculate the spring constant using equation (1) and the data provided for the oscillations without the astronaut:
<em>(it’s important to note that one complete vibration is the period of the movement)</em>
Now with the value of k, we can use again (1) to find the mass of the astronaut (Ma) that makes the period to be 2.54 seconds
Explanation :
Conduction : Conduction is the transfer of heat due to collision between the molecules in the substance.
It is the way of energy transferred in the solid.
Convection : When air is heated and then travels away from the source that means air caries the heat along.
it is called convection.
It is the way of energy transferred in the air and liquid.
Radiation : radiation generate from the emission of electromagnetic wave.
electromagnetic wave carry the energy away from the source which is emitting the radiation.
It is the way of energy transferred in the vacuum.
Yes
Explanation:
John is driving at 25 meters per second and he has to drive 500 meters to get to his house.
I divided 500 by 25 to see how long it would take for John to get to his house
- 500/25= 20
Therefore, it will take John 20 seconds to reach his driveway, which is 25 seconds less than how long it will take his parents- so he will get to the driveway before them.
