Answer:
11.87
Explanation:
final velocity^2= initial velocity ^2+ 2* Acceleration* distance
Final Velocity^2= 9*9+2*1.5.20
final velocity^2 = 141
final velocity = 11.87
Answer:
Explanation:
In electric circuit , the potential difference is always developed across the resistance .
Now is we are to amplify the voltage , that means low input voltage is converted into high voltage output .
Therefore we require low resistance at input for low voltage and high out put resistance for high output
Thus the statement given is wrong .
The answer is genetic engineering
Answer:
Explanation:
a. Given that:
mass of first & second piece,
mass of 3rd piece,
-velocity of first piece(
) and
as velocity of 2nd piece (
)
Let
be velocity of 3rd piece=?
#Vessel is at rest before explosion. Considering conservation of linear momentum:
#Dividing both sides by 

#Plug the
values:

#So the magnitude of the third piece is:

Magnitude of the 3rd piece is 10.84 m/s
b. To find direction of the magnitude (as an angle relative to the
-axis), we find
. The angle is obtained by getting the tan inverse as:

-The direction of the magnitude (angle relative to the x-axis) is 45°
Answer:
This is how I figured it out:
- 215.5 rounded to one significant figure is 200
- 101.02555 rounded to one significant figure is 100.
- 200 + 100 = 300.
Hope this helps!
