Answer:
Explanation:
An acid has H as the metal as in HCl
A base has OH as the nonmetal. (so Ca(OH)^2 is a base)
A salt has neither.
Answer: Energy from the core travels by radiation through the radiative
zone, then by convection through the convection zone.
Explanation:
Considering the frames of reference, the robot has to fire backwards at a speed of 2m/s.
<h3>What is relative velocity?</h3>
The relative velocity is obtained based on the inertial frame of reference. The term velocity is always measured relatively.
Given that the inertial frame of reference is relative to the moving frame then; 7m/s - 9 m/s = -2m/s.
It then follows that the robot has to fire backwards at a speed of 2m/s.
Missing parts:
Basim’s robotics team builds a robot that travels at 9 m/s and can fire a tennis ball at a target.
Which would result in a judge who is sitting beside the testing ground observing the tennis ball having a speed of 7 m/s?
The robot fires the ball forward with a speed of 7 m/s.
The robot fires the ball backward with a speed of 7 m/s.
The robot fires the ball backward with a speed of 2 m/s.
The robot fires the ball forward with a speed of 2 m/s.
