1, 2 & 4 are going to be the the correct answer for the question
Kinetic Energy is defined by Ke=1/2mv^2. Plug in and solve for v.
2,000 = 1/2(1000)(v)^2
4=(v)^2
v=2 m/s
The car must move at 2 m/s to have a Ke of 2,000 Joules.
C because you don’t put a force of which you choose and the force wouldn’t be strong enough
<span>So the question is to unscramble all of the words that are types of heat-creating energy and they are: LACECHMI, CEIECTLR, IRITONFC, AREOGLHMET, LCRNEAU, ROASL. So LACHECHMI is CHEMICAL, CEIECTLR is ELECTRIC, AREOGLHMET is GEOTHERMAL, LCRNEAU is NUCLEAR and ROASL is SOLAR. </span>
Answer:
i = -12.7 cm; h = 5.07 cm
Explanation:
1. Find the focal length
The focal length of a concave spherical mirror is half of its radius of curvature.
f = ½r = ½ × 34.0 cm = 17.0 cm
2. Find the image distance
A convex mirror produces a virtual image behind the mirror, so the image distance is negative.
3. Find the image size
