How is Uranus colder than Neptune

1 answer:

4 0

With Uranus at an average distance of 2.88 billion kilometres from the Sun and Neptune at an average distance of 4.5 billion kilometres it would be very easy to point out which of the gas giants is the coldest, but if you were you were to say that Neptune was the coldest, you’d be wrong.<span>Given that we expect planets further from the Sun to be colder than those closer, this does make Neptune and Uranus quite a mysterious pair. Uranus and Neptune are brimming with volatiles such as water, methane and ammonia and due to their composition in comparison to Jupiter and Saturn, which are comprised mainly of hydrogen and helium, are labelled the ice giants. Scientists have measured how hot Uranus and Neptune should be and have found that Uranus is very cold and very dim</span>

Since most people who are electrocuted don’t blow up, what kills them?

r-ruslan [8.4K]

<span>They are killed mostly by heart attacks. Alternating electrical current interferes with the electrical pulses of the heart produced by the Sino-atrial node hence cause the heart to beat erratically and hence a heart attack and death to result. 7 milliamps to your heart for 3 seconds can cause it to be arrhythmic. </span>

Vector A with arrow lies in the xy plane. Both of its components will be negative if it points from the origin into which quadra

Blizzard [7]

Answer:

Explanation:

From the question we are told that a vector on the x and y plane face their negative axis

Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis

Whilst the negative x axis faces the left which is also alternate to the positive x axis

Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant

In electricity distribution, why is low voltage safer for consumers?

RUDIKE [14]

Answer:

Explanation:

The transmission lines contain about 2500 volts. It is dangerous enough to get zapped by 120 volts. Think what 20 times that much would do to you.

Suppose you want to use this human engine to lift a 2.35 kg box from the floor to a tabletop 1.30 m above the floor. How much mu

morpeh [17]

Answer:

The increase in the gravitational potential energy is 29.93 joules.

Explanation:

Given that,

Mass of the box, m = 2.35 kg

It is lifted from the floor to a tabletop 1.30 m above the floor, h = 1.3 m

We need to find the increase the gravitational potential energy. Initial it will placed at ground i.e. its initial gravitational potential is equal to 0. The increase in the gravitational potential energy is given by :

$U=mgh$

$U=2.35\ kg\times 9.8\ m/s^2\times 1.3\ m$

U = 29.93 Joules

So, the increase in the gravitational potential energy is 29.93 joules. Hence, this is the required solution.
