Probably false. but correct me if i’m wrong
Answer:
R = 7 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance. In this way, we have the following equation.
V = I*R
where:
V = voltage = 49 [V] (units of volts)
I = current = 7 [amp] (amperes)
R = resistance [ohms]
Now clearing R.
R =V/I
R = 49/7
R = 7 [amp]
Answer:
Part a)

Part b)

Part c)

Part d)
Displacement for entire trip = 0
Part e)
Average velocity for entire trip will be zero
Explanation:
Part a)
Displacement after t = 2.4 hours is the straight line distance between initial and final positions
so we have

Part b)
Average velocity is defined as



Part c)
During his return journey the displacement will be same


so average velocity is defined as


Part d)
Displacement for entire trip = 0
as initial and final position will be same
Part e)
Average velocity for entire trip will be zero
Distance travelled in 4 hours...
730 - 442 = 288 miles
Speed for the 4 hours;
Speed = 288/4 = 72 miles/hour
Speed for the rest of 442 miles...;
(72 - 7) = 65 miles/hour
Time taken for 442 miles..
Time taken = Distance/Speed
; 442/65 = 6.8
Time taken = 6.8 hours
Answer:
Every mass
Explanation:
Because Force of gravity always act toward the center of the earth , so when an object is thrown up ,the force of gravity will act in opposite direction of motion ,that's toward the center of earth. The force is towards the center of the Earth (more or less). which gives it time get touch every mass.
