A fishing boat using sonar to locate fish is employing reflection.
Answer:
option C
Explanation:
The correct answer is option C.
For negative velocity
Negative velocity is when the velocity of the object in a negative direction.
so, for the velocity of the car to be negative, it should be in -x-direction.
For positive acceleration
Positive acceleration is the change of the velocity of the object with respect to time in a positive direction
but when the velocity of the object is in negative direction the slowing down of the vehicle will give positive acceleration.
hence, the correct answer is an option -x-direction decreasing in speed.
I = 4.50 amps
R = 6.20 ohms
V = ???
V = I * R
V = 4.5 * 6.2
V = 27.9 volts.
Answer:
0.9 kg
Explanation:
We would use the equation F=m*a to solve this equation. First, we would need to get mass by itself therefore we divide out acceleration from both sides ( F/a=m*a / a ) acceleration would cancel out and the end equation should look like this ( F/a = m or m = F/a) After we do that we plug in the numbers 1.35 N / 1.5 m/s^2 we get 0.9 kg, assuming you are using kg.
