(4.1357 x 10^-15) x (5.4 x 10^2) Answer must be in scientific notation
nadya68 [22]

Answer:

22×10⁻¹³

Explanation:

Scientific notation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.  Thus, in given value,

(4.1357× 10⁻¹⁵) × (5.4×10²)

22×10⁻¹³

What happens in the artificial transmutation of an element? Include an example.
Mice21 [21]
What happens in the artificial transmutation is that the nucleous is bombarded with high energy particles which we can describe as kinetic energy and the idea for them is to induce what we call transmutation. Also what happens is that the high energy particles are accelerated. One of the examples is when nitrogen is transformed into hydrogen by combining its nucleous with an alpha particle
