Answer:
A) .27 A
Explanation:
v = ir
i = v/r
equivalent r = 45 * 90 / (45+90) = 30 ohms ( for the two r in parallel)
i = 8v / 30 ohm = 267 mAmps
Explanation:
Unbalanced Forces in Action
Unbalanced forces can change the motion of an object in two ways. ... Second, when unbalanced forces act on a moving object, the velocity of the object will change. Remember that a change in velocity means a change in speed, direction or both speed and direction.
Answer:
Output voltage is 1.507 mV
Solution:
As per the question:
Nominal resistance, R = 
Fixed resistance, R = 
Gauge Factor, G.F = 2.01
Supply Voltage, 
Strain, 
Now,
To calculate the output voltage,
:
WE know that strain is given by:

Thus

Now, substituting the suitable values in the above eqn:


Answer:2t
Explanation:
Given
Jason throwing watermelon at speed v and it spend t time in air
time to reach max height

0=v-gt'

and time to reach bottom is also t'
t=2t'

For guy throws his watermelon at speed 2v
So total time in air will be


t''=2t
