An ellipse has two focal points. One of the focal points is the <u><em>Sun</em></u>.
Because they planets move faster when they are around the sun.
Answer:
C
Explanation:
Rt= total resistance
we know that 1/Rt=1/R1+1/R2(from ohm's law)
Since, Rt=4 and R1=R2
we will get,
1/4=2/R2
R2=8
when in series Rt=R1+R2,
So, Rt=8+8=16 ohm's
The James Webb Space Telescope (JWST) is a space observatory developed among 20 countries, is being built and operated jointly by NASA, the European Space Agency and the Canadian Space Agency, to be the scientific successor of Hubble and Spitzer. The JWST will offer an unprecedented resolution and sensitivity, some of its main objectives is observe the formation of the first galaxies of the universe and study the formation and evolution of galaxies. The JWST will allow to observe wavelengths within the so-called near-infrared astronomy, but also the orange and red visible light. The importance of this spectrum range is due to the fact that the infrared light can penetrate dusty regions and reveal what is inside. It will be launched in March 2021, the dimensions of its main mirror are 20,197 m × 14,162 m (66.26 ft × 46.46 ft). The JWST will orbit the sun 1.5 million kilometers away from the Earth
