Answer:
The team's model is incorrect because they provide the same materials to build the same product.
Explanation:
Answer:
C. 2.0 cm
Explanation:
The magnetic field around the wire at point M is given by Biot-Savart Law:
where,
B = Magnetic field = 50 μT = 5 x 10⁻⁵ T
I = current = 5 A
μ₀ = permeability of free space = 4π x 10⁻⁷ N/A²
R = distance of point M from wire = ?
Therefore,
R = 0.02 m = 2 cm
Hence, the correct option is:
<u>C. 2.0 cm</u>
Answer:
0.14 kg
Explanation:
a= (Vf²- Vi²)/2.d
the final velocity is 0 (rest), and the initial velocity is 92 mi/h, that is equal to 41 m/s and the distance is 0.15 meters.
a= -5603 m/s² the minos means that the object is decelerating.
then we can use the second Newton law
F= m.a
m= F/a -----> m= 803N / 5603 m/s²
m= 0.14 kg
Answer:
10.284 kgm/s
4.674545 kN
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
m = Mass of baselball
Impulse
Impulse of the baseball is 10.284 kgm/s
Impulse is also given by
The magnitude of the average force exerted by the bat on the ball is 4.674545 kN
