Answer: Speed = 4m/s
Strength = 7.1T
Explanation: P= 4.0w
N = 1.0
V= ?
Power = force x velocity
Velocity = power/ force
V= 4.0w/1.0N
V = 4m/s
Strength of the magnetic field
B = √PR / lv
Where; l = length 10cm
R= 2.0
P= 4.0w
V= 4m/s
B = √ (4.0w) × (2.0) / (10cm) × (4m/s)
B = 7.1T
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Given that:
Io loses about a ton (1000 kilograms) of sulfur dioxide per second to Jupiter's magnetosphere.
In 4.5 billion years, amount of mass lost = 1000 kg/s * (4.5 * 10⁹ * 365 * 60 60 * 24) = 1.41912 * 10¹⁷ kg.
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.

Answer:
B. The current increases.
Explanation:
As we know that rate of flow of charge through the conductor is known as electric current
So we have
here we know that charge Q flowing through the conductor is constant while the time in which it passes through it is decreased
so we can say that the ratio of charge and time will increase
so here we have
So correct answer will be
B. The current increases.
