More empty space in mass !!
Answer:
Solar activity can affect satellite orbits, communication satellites, and the local power grids. It can also impact our spacecraft throughout the solar system, especially orbiters or landers on surfaces without an atmosphere.
Answer
given,
mass of block = 0.21 Kg
speed = 1.70 m/s
spring constant = k = 4.50 N/m
using conservation of energy
a) K.E = P.E
x = 0.367 m
b) if the track is not friction less the maximum compression will be same as the compression in the part a.
Answer:
<h2>line B</h2>
Explanation:
According to ohm's law V = IR where;
V i sthe supply voltage (in volts)
I = supply current (in amperes)
R = resistance (in ohms)
In order to calculate the line that is equal to 2ohms, we need to calculate the slope of each line using the formula.
For line B, R = ΔV/ΔI
R = V₂-V₁/I₂-I₁
R = 14.0-4.0/7.0-2.0
R = 10.0/5.0
R = 2.0ohms
Since the slope of line B is equal to 2 ohms, this shows that the line B is the one that represents the 2ohms resistor.
Answer: the focal length of the CCl4-glass combination is 102.31 cm
Explanation:
Given that;
Index of refraction n1 = 1.55
carbon tetrachloride (CCl4), which has n2 = 1.46
radii of curvature for its surfaces R1 = 4.6cm and R2 = 9.20 cm
the focal length of the CCl4-glass combination = ?
we can determine the focal length using the Formula;
1/f = ( n1 - n2) ( 1/R1 - 1/R)
so we substitute in our values
1/f = ( 1.55 - 1.46 ( 1/4.6 - 1/9.20)
1/f = 0.09 × 0.1086
1/f = 0.009774
f = 1 / 0.009774
f = 102.31 cm
Therefore the focal length of the CCl4-glass combination is 102.31 cm
