We know, F = m * a
F = 10 * 5
F = 50 N
In short, Your Answer would be 50 Newtons
Hope this helps!
Coulomb's Law: Force = k x q1x q2 divided distance square
where k=9x10^9 , q1 and q2 are the charge
So if you distance is halved, your force is stronger by 4 times
and if you distance is doubled, your force is 1/4
Ask me again if you aren't clear :)
Answer:
16.26 cm in front of the mirror
Explanation:
Using,
1/f = 1/u+1/v....................... Equation 1
Where f = focal focal length of the concave mirror, u = object distance, v = image distance.
make v the subject of the equation
v = fu/(u-f)................... Equation 2
Note: The focal length of a concave mirror is positive
Using the real- is- positive convention
Given: f = 22/2 = 11 cm, u = 34 cm.
Substitute into equation 2
v = (34×11)/(34-11)
v = 374/23
v = 16.26 cm.
The image will be formed 16.26 cm in front of the mirror.
Answer:
4.78 × 10⁻³ T.m²
Explanation:
The expression for the magnetic flux is given by
∅ = BAcosФ
where B = magnetic field strength
A = Area of circular loop = πr²
r = radius of the wire loop
substitute πr² for A in the first equation
∅ = Bπr²cosФ
∅ = 2.55 × 3.14 × 0.025² × cos 17.3°
∅ = 4.78 × 10⁻³ T.m²
OR
0.00478 T.m²
