To solve this problem we will apply the concepts related to the Voltage depending on the Electric field and the distance where it is applied. The relationship of this relationship is given in the following form:
Here,
E = Electric Field
V = Voltage
d = Distance
Our values are given as,
Replacing at the first equation we have,
Therefore the electric field in the strip is 2.866V/m
Answer:
Glucose
Explanation:
During exercise, muscles need more energy. They get this energy by aerobic respiration, which uses oxygen and glucose to release energy.
Note: If the body fails to supply oxygen to the muscles fast enough, the muscles will produce energy by anaerobic respiration, which is not as effective as aerobic respiration in addition to producing lactic acid.
Answer:
I believe it is kinetic
Explanation:
Kinetic energy is in physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
So if something is doing work it has kinetic energy
Answer:
y = -0.42 m
1.16*10^-4 T(-k)
-1.73*10^4 N/C (j)
Explanation:
(a) Above the pair of wires, The field out of the page of the 50 A current will be stronger than the (—k) field of the 30 A current (k).
Between the wires, both produce fields into the page.
below the wires, y = - | y |
B = u_o*I/2πr (-k) + u_o*I/2πr (k)
0 = u_o/2πr[50/ | y |+0.28 (-k) + 30/| y | (k) ]
50 | y | = 30(| y | + 0.28)
| y | = -y
-50 y = 30*(0.28 - y)
y = -0.42 m
b) B = u_o*I/2πr (-k) + u_o*I/2πr (k)
B = 4π*10^-7/2π[ 50/0.28 -1 (-k) +30/1(-k) ]
= 1.16*10^-4 T(-k)
F = qv*B
F = (-2*10^-6)*(150*10^6(i) )(1.16*10^-4(-k))
F = 3.47*10^-2 N(-j)
c) F_e = qE
E = F_e/q
E = 3.47*10^-2/-2*10-6
= -1.73*10^4 N/C (j)
Answer:
2.4m/s towards the bowling pins
Explanation:
Given parameters:
Mass of the ball = 6.6kg
Momentum of the ball = 15.9kgm/s
Unknown:
Speed of the ball = ?
Solution:
The momentum is the amount of motion a body posses;
Momentum = mas x velocity
Insert the parameters and solve;
15.9 = 6.6 x velocity
velocity = 2.4m/s towards the bowling pins
