There are 6 types of quarks.
Answer: C. 6
Answer:
p = 20 kg•m/s
KE = 100 J
Explanation:
In an elastic collision of identical masses, the two masses will exchange momentums. Therefore Block 1 initially moving at 10 m/s will be moving at 2 m/s, and Block 2 will go from 2 m/s to 10 m/s
momentum = mv = 2(10) = 20 kg•m/s
KE = ½mv² = ½(2)10² = 100 J
Unfortunately, your answer selection does not have this answer as an option.
Answer:
option B is correct
factor is 0.0625
Explanation:
Given data
camera lens = 4X
to find out
find factor
solution
we know Inverse square law that is the intensity is inversely proportional to the square of the distance from the source i.e f
so we say intensity ( I ) ∝ 1 / f
so I1 / I2 = f2² / f1²
so I2 will be
I2 = f2² / f1² × I1
I2 = 1 / 4² × I1
I2 = 0.0625
so option B is correct
factor is 0.0625
Answer: D. 0.5
Explanation:
The slope formula is y2-y1/x2-x1.
2-(-1)/4-(-2) = 2+1/4+2
2+1/4+2 = 3/6 = 1/2
1/2 = 0.5
The slope is 1/2, or 0.5.
