Answer:
1) move away from the windows.
When abrupt changes in pressure (produced by the hurricane) affect the windows, they can "explode" and be a serious danger for the people.
2) Go to the lowest level of the building.
Is safer than the upper levels because the lower levels suffer less from the strength of the hurricane (being closer to the ground increases the structural resistance), make sure that you have everything you may need in case of an emergency.

Answer:
..
Explanation:
Coordinate adjectives are adjectives that describe the same noun equally. They should be separated with commas. In this sentence, both red and round are describing the ball. The correct answer is, "The red, round ball is Adley's favorite toy to play with."
Answer:
185.95 μsec
Explanation:
Given that:
Sine wave =
Sinusodial signal = 50 kHz =
Rise time is said to be defined as the time needed for a pulse to rise from 10% - 90% of maximum rate.
∴
= 10% = 0.1 Am
=90% = 0.9 Am
Using sine wave for ; we have:
= 0.1 Am
= 0.1
= 5.7392
Using sine wave for ; we have:
= 0.9 Am
=
= 64.158
=
=
Change in rise time = -
=
=
=
since; = 50 kHz =
=
= 1.85952 × 10⁻⁴
= 185.952 × 10⁻⁶ sec
= 185.95 μ sec
∴ The rise in time in (μ sec) for the sinosodial signal at 50 kHz = 185.95 μ sec
