Mass doesn't depend on where it is, and doesn't change.
After impact velocity = 14.968 ft/s
Weight and mass of Bullet and wooden block:
Bullet: w = 1oz = 1/16 lb m = 0.001941 lb
wooden block : W = 5lb M = 0.15528 lb
velocity of block and bullet immediately after impact:
Σmv1 + ΣImp = mv2
Resolving vertical component
( m× v₀cos30⁰) + 0 = ( m+M) v'
v' = ( m× v₀cos30⁰)/ (m+M)
v' = 14.968 ft/s
Horizontal and vertical component of the impulse exerted by block on the bullet:
Here we will apply the principle of impulse and momentum.
Horizontal component:
-mv₀ cos30⁰ + RxΔt =0
RxΔt = mv₀sin30⁰
= 0.001941 × 1400sin30⁰
RxΔt = 1.3587 lb.s
Vertical component:
-mv₀cos30⁰ + RyΔt = -mv'
RyΔt = m( v₀cos30⁰-v')
RyΔt = 0.001941(1400cos30⁰ - 14.968)
= 2.32 lb.s

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.

Answer:
Resistance will become 4 times of first wire resistance.
Explanation:
At the temperature of both the the tungsten wire is same so we can apply ohm's law
Let the length of first wire is and cross sectional area is
Resistance of first wire ......1
Now length of second wire is twice the length of first wire
and cross sectional area .......2
Resistance of wire 2 ........2
Dividing equation 1 by equation 1
Therefore resistance will become 4 times.
Answer:
File transfer protocol secure (FTPS)
Explanation:
File transfer encryption is an essential security measure that prevents outsiders from being able to read or understand the data that is being transferred. This protects the information from potential hackers.
There are three options for encrypting file transfer data: FTPS (File Transfer Protocol Secure), FTP (File Transfer Protocol) and HTTPS (HTTP Secure).
File Transfer Protocol (FTP) and File Transfer Protocol secure (FTPS) are used for transferring files. However FTPS is the only secure, encrypted protocol.
