Answer:
It has very high density, so a small bulb of a thermometer can contain much mercury. Mercury remains liquid state over a quite wide range of temperature because it freezes at 39°C and boils at 357°C.
Explanation:
1. "Weather is the area’s day-to-day conditions and climate is the area’s average conditions" is how <span>an area’s weather differ from the area’s climate. The correct option among all the options given in the question is option "D".
2. </span>All of the following factors contribute to Earth’s climate except longitude. <span>The correct option among all the options given in the question is the second option.</span>
The water pressure at this depth and the total pressure due to water and atmosphere are 10.3 x 10⁵ Pa and 11.31× 10⁵ Pa.
<h3>What is pressure?</h3>
The pressure is the amount of force applied per unit area.
Atmospheric pressure, Patm =1.01×10⁵ Pa
Density of water, ρ=1030 kg/m³
Depth, h=100 m
Pressure =ρgh
P = 1030×10×100
P = 10.3 x 10⁵ Pa.
Total pressure, P=Po +ρgh
P=1.01×10⁵ + 1030×10×100
P=11.31× 10⁵ Pa
Hence, total pressure is 11.31× 10⁵ Pa.

Answer:
the height of the potential energy is 3,200 J
Explanation:
The computation of the kinetic energy is shown below:
Kinetic energy = 1 ÷ 2 × mass × velocity^2
= 1 ÷ 2 × 4 kg × 40 m/s^2
= 3,200 J
Hence the height of the potential energy is 3,200 J
