Answer:
168 Volts
Explanation:
Use Ohm's law:
(Voltage) = (Current) x (Resistance)
(Voltage) = 21 A * 8 Ohm = 168 V
<span>To find the amount of work done by a force acting on a moving object, we can use this simple equation:
W = F * d * cos(theta)
W is Work
F is the force
d is the distance the object moves
theta is the angle between the force vector and the direction of motion
We know that (F * d) is 190 joules. We can find the work done when the angle is 56°.
W = F * d * cos(theta)
W = (190 J) * cos(56°)
W = 106 J
At an angle of 56°, the work done by the force is 106 joules.</span>
F= 6m.m2/r^2
F= (6.673x10^-11)(70)(3.32x10^23)/(2.44x10^6)^2
ANS: F= 260 N=2.60x10^2 N
The student's responses should explain that both Wilhelm Wundt and John Watson will disagree with Julie's claim of psychology not being a science.
Moreover,the student's answers should typically in a way acknowledge Wilhelm Wundt use of experimental method and also acknowledge the emphasis John Watson made on observable behaviours.
The object rises to a height of 20.4 m. So option C is correct.
Explanation:
initial velocity= Vi=20 m/s
final velocity at the top= Vf=0
acceleration= g=-9.8 m/s²
Vf²=Vi²+2gh
0= (20)²+2 (-9.8)h
-200=-9.8h
h=200/9.8
h=20.4 m
Thus the object rises to a height of 20.4 m
