Answer:
0.000133046 V
Explanation:
B = Magnetic field = 7 T
t = Time = 20 s
d = Diameter = 2.2 cm
r = Radius =
A = Area =
Induced emf is given by
The induced emf is 0.000133046 V
<span>m^(- 5) = 1/35 → you know that: x^(- a) = 1/x^(+ a) = 1/x^a
1/m^5 = 1/35 → you take the inverse
m^5 = 35
[m^5]^(1/5) = 35^(1/5) → recall: (x^a)^b = x^(ab)
m^[5 * (1/5)] = 35^(1/5)
m^[1)] = 35^(1/5)
m = 35^(1/5)
The scientific notation is a number between 1 and 9 with few numbers after coma (point) completed by a power 10.
= [1.4 * 10^(3)] * [2.5 * 10^(- 6)] → you remove the brackets
= 1.4 * 10^(3) * 2.5 * 10^(- 6) → you order
= 1.4 * 2.5 * 10^(3) * 10^(- 6) → you make the multiplication
= 3.5 * 10^(3) * 10^(- 6) → recall: (x^a) * (x^b) = x^(a + b)
= 3.5 * 10^(3 - 6)
= 3.5 * 10^(- 3) ← answer C</span><span>

In the object that has, the least inertia.
The "q" would be the electric charge. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges<span>: positive and negative.
Therefore on the statement above, the value of the electric charge would be </span><span>1.0 nC.

Answer:
<em>A. 22 </em>
<em>B. NO</em>
Explanation:
<u>A.</u>
During a collision , <em>the net external force on the system is zero .</em>
hence , the total momentum of the system can be CONSERVED .
let the mass of frosty and snowflake be m ;
- initial velocity of frosty be = 25
- final velocity of frosty be = 13
- initial velocity of snowflake be = 10
- final velocity of snowflake be = x
therefore from principle of conservation of momentum ,
<em></em>
so ,
<u>answer for A. 22 </u>
<u>B</u>.
<em>The collision is NOT ELASTIC.</em>
this is because if it had been elastic , the coefficient of restitution should have been 1 but it isnot i.e
≠ 1
<em>thus it's an inelastic collision.</em>
