using the law of refraction, the incidence is equal to the reflection, but not refraction
Answer:
94.67 N
Explanation:
Consider a free body diagram with force, F of 41 N applied at an angle of 37 degrees while the weight acts downwards. Resolving the force into vertical and horizontal components, we obtain a free body diagram attached.
At equilibrium, normal reaction is equal to the sum of the weight and the vertical component of the force applied. Applying the condition of equilibrium along the vertical direction.
Substituting 70 N for W, 41 N for F and for 37 degrees
N=70+41sin37=94.67441595 N and rounding off to 2 decimal places
N=94.67 N
Answer:
3 outcomes
Explanation:
Since the sum must be less than 7, then one of them cannot be 7 because 7 + something > 7. Also the minimum number is 2 so one of them cannot be 5 either because 5 + 2 = 7 is not less than 7.
So the only options we have here is 2 and 4. The outcome of this is
(2,2) so 2 + 2 = 4 < 7
(2,4) so 2 + 4 = 6 < 7
(4,2) so 4 + 2 = 6 < 7
Note that (4,4) is not possible because 4 + 4 = 8 > 7
So 3 outcomes have a sum less than 7 and contain at least one even number
It is B) Wavelength, because it measures the "length" between "waves", therefore, wavelength.
Answer:
The force experienced is 0.6 N
Explanation:
Given data
length of wire L= 2 m
current in wire I= 0.6 A
magnetic field B= 0.5
The force experienced can be represented as
