From the moment it leaves Terry's hand ... all the way up and then all the way down ... until the moment the ball hits the ground, its acceleration is 9.8 m/s^2 downward. That's the acceleration of gravity (on Earth), and gravity is the only force acting on the ball.
By the way ... Terry needs to control his rage and go get a job as a pitcher for Major League Baseball. That 100 m/s of his is more than double the speed that professional pitchers typically deliver !
Earthquakes are normally associated when two tectonic plates move away from each other causing a rift in the plate and you get an earthquake.
<h2>
Answer: B) It would be best to use a concave mirror, with the object to be ignited positioned halfway between the mirror and its center of curvature. </h2>
Explanation:
To start a fire it is more optimal to use a concave mirror than a plane mirror. This is because the concave mirror allows concentrating sunlight at a point (the focal point) on an object that acts as fuel and ignite the fire there.
For this it is necessary the object to be positioned between the center of curvature of the mirror and the mirror (its focus). Thus the rays of the Sun, when converging on the focus, will heat the object and make it burn.
Hence, the correct option is B.
Since the direction of the needle depends on the proximity of the magnet thus this test alone is insufficient to determine the stronger magnet.
<h3>What is a magnetic field?</h3>
A magnetic field refers to the region where the effect of a magnet is felt. The magnetic field can be observed by the use of a compass.
Now, we know that the closer the magnet is to the compass, the greater the deflection hence this test alone is insufficient to determine the stronger magnet.
