Answer with Explanation:
We are given that
Initial speed=
a.
Final velocity of ball=

g is negative because the ball is going against to gravity.




Using the formula


a.The ball rise upto height 18.4 m
b.It take 1.94 s to reach its highest point.
c.Initial velocity=0,s=18.4 m







Using the formula

Answer:
Explanation:
go around your house and tap random objects. For example, a sink. What noise did it make? was it loud or quiet? was it soft or hard? I hope this helps
Answer:
Approximately
.
Explanation:
It is given that
and
are connected in a circuit in parallel.
Assume that this circuit is powered with a direct current power supply of voltage
.
Since
and
are connected in parallel, the voltage across the two resistors would both be
. Thus, the current going through the two resistors would be
and
, respectively.
Also because the two resistors are connected in parallel, the total current in this circuit would be the sum of the current in each resistor:
.
In other words, if the voltage across this circuit is
, the total current in this circuit would be
. The (equivalent) resistance
of this circuit would be:
.
Given that
and
:
.
Answer:
A comet is cruising through the solar system at a speed of 50,000 kilometers per hour for 4 hours time. What is the total distance traveled by the comet during this time?
✓ Distance = Speed * Time Distance = 50,000 * 4 Distance = 200,000 km. Hope this helps
