During primary second stage underwater recovery, it is acceptable to switch to your alternate air source while you search for your primary which makes it a true statement.

<h3>What is Primary second stage underwater?</h3>

This involves the intermediate pressure air from the regulator hose being taken and reduced to ambient pressure.

Switching to your alternate air source  will ensure that the diver breathe safely which is why True was chosen.

Jumping up before the elevator hits. After the cable snaps and the safety system fails, an elevator cab free-falls from a height
butalik [34]

Answer:

a) I = -2257.6 Kg*m/s

b) F = -451,520N

Explanation:

part a.

we know that:

I = P_f-P_i

where I is the impulse, P_f the final momentum and P_i the initial momentum.

so:

I = MV_f-MV_i

where M is the mass, V_f the final velocity and V_i the initial velocity.

Therefore, we have to find the initial velocity or the velocity of the passenger just before the collition.

now, we will use the law of the conservation of energy:

E_i=E_f

so:

mgh = \frac{1}{2}MV_i^2

where g is the gravity and h the altitude. So, replacing values, we get:

(85kg)(9.8m/s^2)(36m)= \frac{1}{2}(85kg)V_i^2

solving for V_i:

V_i = 26.56m/s

Then, replacing in the initial equation:

I = MV_f-MV_i

I = (85kg)(0m/s)-(85kg)(26.56m/s)

I = -2257.6 Kg*m/s

Then, the impulse is -2257.6 Kg*m/s, it is negative because it is upwards.

part b.

we know that:

Ft = I

where F is the average force, t is the time and I is the impulse. So, replacing values, we get:

F(0,005s) = -2257.6 Kg*m/s

solving for F:

F = -451520N

Finally, the force is -451,520N, it is negative because it is upwards.

The logarithm of x, written log(x), tells you the power to which you would raise 10 to get x. So, if y=log(x), then x=10^y. It i
fomenos

To solve this problem it is necessary to apply the rules and concepts related to logarithmic operations.

From the definition of logarithm we know that,

Log_{10}(10) = 1

In this way for the given example we have that a logarithm with base 10 expressed in the problem can be represented as,

log_{10}(1,000,000)

We can express this also as,

log_{10}(10^6)

By properties of the logarithms we know that the logarithm of a power of a number is equal to the product between the exponent of the power and the logarithm of the number.

So this can be expressed as

6*log_{10}(10)

Since the definition of the base logarithm 10 of 10 is equal to 1 then

6*1=6

The value of the given logarithm is equal to 6
