If a car goes at a speed of 80 kph in 10 seconds, what is the distance

Physics
1 answer:
Blababa [14]3 years ago
3 0

Answer:222 meters

Explanation:

Speed=80kph=(80x5/18)=(80x5)/18=22.2m/s

Time=10 seconds

distance=speed x time

distance=22.2 x 10

distance=222

distance=222 meters

Question 2 (1 point)
Tju [1.3M]

Answer:

I know someone anwsered but it would be 400M

Explanation:

i initial velocity (u)=10m/s

acceleration (a)=0

time taken (t) =40s

then distance (s)=u t +1/2 a t^2

s= u t +0 (as a is 0)

s= 10 x 40

s= 400M

zimovet [89]

Although you walked (14+9)= 23 meters of distance, you ended up only 16.64 meters from where you started. That's your "displacement".

Velocity = (displacement / (time)

Velocity = (16.64m)/(180s)

Velocity = 0.0925 m/s roughly Southwest.

(That's about 3.6 INCHES per second. Apparently, you really NEED that mocha java and it's associated drug.)

A circuit has a current of 2.4 A. The voltage is increased to 4 times its original value, while the resistance stays the same. H
9966 [12]

Answer:

Resistance will become 4 times the previous value

Explanation:

We have given current in the circuit i = 2.4 A

According to ohm's law current in the circuit is given by I=\frac{V}{R}

So 2.4=\frac{V}{R}............eqn 1

Now voltage is increased to 4 times so new voltage = 4 V

And current in the circuit is same as 2.4 A

We have to fond the resistance so that after increasing voltage current will be same

So 2.4=\frac{4V}{R_{unknown}}..........eqn 2

Dividing eqn 1 and 2

1=\frac{V}{R}\times \frac{R_{unkown}}{4V}

R_{unknown}=4R

So resistance will become 4 times the previous value
