Lightning bolts can carry currents up to approximately 20 kA. We can model such a current as the equivalent of a very long, stra

GalinKa [24]

Answer:

how large a magnetic field would you experience = 8.16 x 10∧-4T

Explanation:

I = 20KA = 20,000A

r = 4.9 m

how large a magnetic field would you experience = u.I/2πr

how large a magnetic field would you experience = (4π x10∧-7) × 20000/2π × 4.9

how large a magnetic field would you experience = 8.16 x 10∧-4T

2) Why do you think fossil fueled cars are still out numbering alternative and replacement fueled cars even though fossil fuels

Misha Larkins [42]

Answer:

Fossil-fueled cars are still outnumbering the alternative and replacement-fueled cars because they are generally cost-effective and are efficient.

Explanation:

Fossil fuels are non-renewable energy that cannot be replenished. Although many people know how harmful using them can be to the environment, still, people continue to buy cars that are powered by it. This is because, using fossil-fueled cars can help you save money compared to using replacement-fueled cars. Its engines are also more powerful, which means they can arrive at their destination in just a few minutes. This makes it efficient. The cost of maintaining a fossil-fueled car is less expensive compared to replacement-fueled cars. People are naturally keen when it comes to budgeting, thus, many people still buy cars powered by fossil fuels.

Aiden takes 0.10s to throw a baseball, which leaves his hand with a velocity of 49m/s. The balls acceleration is

Brums [2.3K]

Since the ball was not moving before it let Aiden's hand, the formula used to calculate the acceleration is
$a = \frac{v}{t}$
, where a is acceleration, v is velocity and t is the time. We put them in the formula and get
$a = \frac{49}{0.1} \\ a = \frac{490}{1} \\ a = 490$
The acceleration is 490 m/s^2
