Answer:
y = 2.2t + 30.2
Explanation:
t = 3 represents 1983, and t = 9 represents 1989.
Two points on the line are (3, 36.8) and (9, 50).
First, find the slope of the line.
m = (50 − 36.8) / (9 − 3)
m = 2.2
Now use point-slope form to write the equation:
y − 36.8 = 2.2 (t − 3)
If you wish, simplify to slope-intercept form:
y − 36.8 = 2.2t − 6.6
y = 2.2t + 30.2
Answer: A. Strong nuclear
The max effective range of strong nuclear force is about 1.2 femtometers ( which is 1.2*10^(-15) meters). This is well below 1 meter. Strong nuclear forces are the forces that hold together a nucleus. Specifically it holds together the protons that would otherwise repel one another due to similar charge.
Answer:
True
Explanation:
The image produced a convex mirror is always virtual irrespective of location. The size of the image is always smaller than the object. In a plane mirror the distance of the object and the distance of the image is same. But in a convex the image distance is always less than the object distance.
So, this statement is true.
Answer:
Explanation:
Magnetic field due to a moving charge
B = μ₀ / 4π x (qv x r)/r²
Given
B = .3 X 10⁻⁶ T,
r = 60 x 10⁻³ m
Putting these values in the given equation
.3 x 10⁻⁶ = 10⁻⁷ x qvsinθ /( 60 x 10⁻³)²
θ = 90 °
qv = 10.8 x 10⁻³
At point P
Sinθ = 60 / 72
r² = 72 x 72 x 10⁻⁶
B = 
= 0.17 μT
