<u>Answer:</u>
The ball is rolling at a speed of 0.02 meter per second.
<u>Step by step explanation:</u>
We are given that there is a 800 gram bowling ball rolling in a straight line. If its momentum is given to be 16 kg.m/sec, we are to find its velocity.
For this, we will use the formula of momentum.
<em>Momentum = mass × velocity</em>
16 = 800 × velocity
Velocity = 16/800 = 0.02 meter per second
Answer:
Projectile motion is a form of motion where an object moves in a bilaterally symmetrical+ parabolic path.
Explanation:
a. linear pairs, when added together, the angles will make 180 degrees, or a straight line. In this case No, for when you combine the two angles, it is not a straight line
b. False. Vertical angles make two opposite angles that are congruent
c. True. When added together, angles 1 and 4 make a straight line
d. False. As stated for question b, the two opposite angles must be congruent
hope this helps
Answer:
0.73 W/m²
0.2522 W/m²
Explanation:
= Unpolarized light = 1.46 W/m²
= Analyzer angle = 54°
Light through first filter
The intensity of the light leaving the polarizer is 0.73 W/m²
After passing through analyzer
The intensity of the light that reaches the photocell is 0.2522 W/m²
Weight = mass × gravity
Earth:
W = 70 × 9.8
= 686 Newtons
