The answer is B, the vector represents magnitude and direction
From the information given,
diameter of ornament = 8
radius = diameter/2 = 8/2
radius of curvature, r = 4
Recall,
focal length, f = radius of curvature/2 = 4/2
f = 2
Recall,
magnification = image d
Answer:
I=2.80 A
Explanation:
We Know that R =R₀(1+∝ ΔT)
R=R₀ (1+3.9*10⁻³ *(61-20))
R=R₀ (1.1599)
I=V/R=V/(R₀ (1.1599)
1.4 = V/(R₀ (1.1599) ∵ equation 1
We have to calculate I when T=-88°
R =R₀(1+∝ ΔT)
R=R₀ (1+3.9*10⁻³ *(-88-20))
R=R₀ (0.5788)
I=V/(R₀ (0.5788) ∵equation 2
Dividing equation 2 by equation 1

I = 2.80 A
sun and comet also meteroid
Answer:
1. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.
2. potential energy
3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
4. Refraction is the bending of light
5. Density uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). Density is defined as mass per unit volume.
