Answer:
Since the resistors are in series, all of them carry the same current I.
if the potential drop across the 12 Ω is 4 V
I = 4 / 12 = 1/3 = .333 amp
a) 25 Ω * .333 amp = 8.33 V
b) 62 V * .333 amp = 20.7 V
Answer:
d = 68.18 m
Explanation:
Given that,
Initial velocity, u = 15 m/s
Finally it comes to stop, v = 0
Acceleration, a = -1.65 m/s²
Time, t = 2.5 s
We need to find the distance covered by the hayride before coming to a stop. Let d is the distance covered. Using third equation of motion to find it :
So, the hayride will cover a distance of 68.18 m.
Positive reinforcement you give praise and treats when they get something right negative you punish them for getting something wrong. Positive builds confidence and drive to get something right and negative builds fear of doing something wrong
Answer
given,
constant net force = 75 N
distance = 0.60 m
mass = 0.20 Kg
a) by work energy theorem work done is equal to change in kinetic energy.
initial speed = 0 m/s
b) We know.
v² = 450
v = 21.21 m/s
the final speed of the object is equal to v = 21.21 m/s
The molecular geometry of both F2 and HF is linear.There are only two atoms which are covalently bonded and thus, the bonding scheme with the atoms looks like this;
F --- F
H---F
So, both are linear.
