<u>Answer</u>:
Newton proposed the "law of Universal Gravitation". He said that gravity is universal in nature and it affects all the objects. Gravity is present between you and every object having mass around you. The "Strength of the gravity" between two objects with mass is depends on the product of masses and distance between the objects.
The "Gravitational force" increases with the increase in mass of the objects and decreases with the increase in distance between the objects. The gravity exerts a force on every object. The direction of force of gravity is towards the centre of the Earth.
Answer:
water leak is 650 gallons
time required to full drain is 80 hrs
Explanation:
given data
volume V = 3200 gallon
rate = V(t) = 80 - t
to find out
how much water leak between 10 and 20 hour and drain complete
solution
we know here rate is 80 - t
so here rate will be
= 80 - t
and for time 10 and 20 hour
take integrate between 10 and 20
so water leak = 
.....................1
water leak = ( 80t - 
water leak = 650
so water leak is 650 gallons
and
we know here for full tank drain condition
water leak full = 80 t - 
3200 = 80 t -
6400 = t² - 160 t
t = 80
so time required to full drain is 80 hrs
-- The acceleration due to gravity is 32.2 ft/sec² . That means that the
speed of a falling object increases by an additional 32.2 ft/sec every second.
-- If dropped from "rest" (zero initial speed), then after falling for 4 seconds,
the object's speed is (4.0) x (32.2) = <em>128.8 ft/sec</em>.
-- 128.8 ft/sec = <em>87.8 miles per hour</em>
Now we can switch over to the metric system, where the acceleration
due to gravity is typically rounded to 9.8 meters/sec² .
-- Distance = (1/2) x (acceleration) x (time)²
D = (1/2) (9.8) x (4)² =<em> 78.4 meters</em>
-- At 32 floors per 100 meters, 78.4 meters = dropped from the <em>25th floor</em>.
The 5 points are certainly appreciated, but I do wish they were Celsius points.
Produced the model is the resistance of the circuits decreased as a battery voltage increased (option-B).
<h3>What connection does there exist between voltage and current, current and resistance, and voltage and resistance?</h3>
Ohm's Law describes how current, voltage, and resistance are related to one another. According to this, as long as the temperature doesn't change, the current flowing through a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
The more work a certain quantity of electrons can accomplish at a given voltage. The quantity of electrons that are presently moving through any one point in a circuit at any particular time is known as the current. At the same voltage, a larger current can perform more work. Current times voltage equals power.

For both, remember that velocity is a vector force, meaning that it has both a magnitude and direction. Since direction is part of the vector, if the direction changes so does the velocity in general. The changing of velocity is acceleration, so for 1 the answer is False.
For 2 I'm not sure what you meant, but the answer is the acceleration changes but the velocity does not.
