Answer:
V= 33.98 m/s
Explanation:
Given that
Horizontal speed ,u= 17 m/s
Time taken by rockets to strike the water ,t= 3 s
We know that acceleration due to gravity ,g= 9.81 m/s²
There is no any acceleration in the horizontal direction that is why the horizontal veloity will remain constant.
In the vertical direction
vy = uy+ g t
Initial velocity in vertical direction is 0 m/s.
vy= 0+ 9.81 x 3
vy = 29.43 m/s
The resultant velocity
![V=\sqrt{v_y^2+u^2}](https://tex.z-dn.net/?f=V%3D%5Csqrt%7Bv_y%5E2%2Bu%5E2%7D)
![V=\sqrt{29.43^2+17^2}\ m/s](https://tex.z-dn.net/?f=V%3D%5Csqrt%7B29.43%5E2%2B17%5E2%7D%5C%20m%2Fs)
V= 33.98 m/s

See attached handwritten document for answer
Explanation:
Voltage is given by the formula
V = IR (Ohms law)
where V is the Voltage
I is the current
and R is the Resistance
Here it is given that the current is I=11
Resistance is R =12
so plugging this in the formula
V = IR
V= 11 * 12
V= 132 Volts
So the Voltage for the given dryer is 132 Volts
Answer:
Just red light is reflected. Even if you shine a red laser at a blue piece of paper, only red light is reflected. ... The dot you see will probably always be red. If you do this in a bright room, you might trick yourself.
