Answer:
the ans is D... good luck
<h2>Given :</h2>
- total charge = 9.0 mC = 0.009 C
Each electron has a charge of :

For producing 1 Cuolomb charge we need :
Now, for producing 0.009 C of charge, the number of electrons required is :
_____________________________
So, Number of electrons passing through the cross section in 3.6 seconds is :

Number of electrons passing through it in 1 Second is :
Now, in 10 seconds the number of electrons passing through it is :

Answer:
Well first for criteria think what would the rover need in order to sustain itself on Venus. And for constraints think of anything that could possibly affect the rover( ex: gasses, active volcanoes)
Explanation:
Criteria: Make the rover self sustainable, and allow the rover to have a mission on Venus( ex: collect rock samples)
Constraints, as I mentioned above gasses, and active volcanoes.
I hope this helps! :)
Answer:
The force exerted by the floor is 80 N.
Explanation:
Given that,
Mass of ball = 0.5 kg
Velocity= 4 m/s
Time t = 0.05 s
When the ball rebounds then the kinetic energy is

Where, m = mass of ball
v = velocity of ball
Put the value into the formula


The average force exerted by the floor on the ball = change in kinetic energy over collision time


Hence, The force exerted by the floor is 80 N.
Answer:
Remote Location Monitoring
Explanation:
Remote Location Monitoring involves the use of electronic equipment to verify that an offender is at home or in a community correctional center during specified hours o to track his her whereabouts.
Using programmed contact to verify an offenders location that distant, varied by the use of Global positioning system (GPS) to continuously map the exact location of the offender.
