Answer:
So, you're going to need the equation ρ = ρo [1 + α(T-To)]
1.59x10^-8 ohms*m is your ρo because that is measured at your reference temperature (To), 20◦C. T is your 6◦C and α is 0.0038(◦C)−1. So, using that you solve for ρ. If you keep up with the units though, you notice it comes out to be ohms*m and that isn't what you want.
So, the next equation you need is J=σE where E is your electric field (3026 V/m) and σ is the electrical conductivity which is the inverse of your answer you got in the previous equation. So find the inverse of that answer and multiply it by your electric field and that will give you the current density.
I hope this helps!
Explanation:
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
Answer:

diagram showing the correlation between two quantities
Explanation:
Graph is the plot of two physical quantities and it describes the relation between both quantities. It gives a specific relation between the two physical quantities which is used to analyze the result.
Thus, the following options are correct,
analyzing what data means
diagram showing the correlation between two quantities
Answer:
P = 11666.6 W
Explanation:
Given that,
Work done by the motor, W = 3500 kJ
Time, t = 5 min = 300 s
We need to find the power developed by the motor. Power developed is given by :

So, the required power is 11666.6 W.
