How are desert plants adapted to their climate? Describe the climate and give specific examples
Stella [2.4K]
Desert plants are adopted to their climate because they live in it for so long, they know how to live without certain things like water. A deserts climate is hot and dry and like cacti, they live in the desert without water and in such heat because they do not need it to live.

Which of the following are a units of energy? Select all that apply.
nikdorinn [45]

Answer:

Hey there

Your answer should be Joules, Watts, and J/s.

The joule

The joule (pronounced jool) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton-metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).

The Watt

The watt (symbol: W) is a unit of power or radiant flux. In the International System of Units (SI), it is defined as a derived unit of (in SI base units)[1][2] 1 kg⋅m2⋅s−3 or, equivalently,[3] 1 joule per second (J/s). It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736-1819), an 18th-century Scottish inventor.

A simple pendulum consists of a point mass suspended by a weightless, rigid wire in a uniform gravitation field. Which of the fo
alex41 [277]

Answer:

The period is proportional to the square root of the length of the wire.

The period is independent of the suspended mass.

Explanation:

The period of a simple pendulum, in the small angle oscillation approximation, is given by

T=2\pi \sqrt{\frac{L}{g}}

where

L is the length of the pendulum

g is the acceleration due to gravity

From the formula, we notice the following facts:

- The period is proportional to the square root of the length of the wire, L

- The period is independent of the suspended mass, m

So, these are the two correct statements.

A car’s headlights dissipate 40 W on low beam and 50 W on high beam. Is there more or less resistance in the high-beam filament?
love history [14]

Answer:

The high-beam filament has more resistance than low beam filament.

Explanation:

To determine if the 50 W dissipated by a car’s headlights on high beam, has more or less resistance, formula for power dissipated in the filament is used.

Power = IV

Voltage =IR

∴ Power = I*IR = I²R

where;

I is the current

V is the voltage

R is the resistance

From the equation above, Power dissipated is directly proportional to Resistance.

Hence, the high-beam filament has more resistance than low beam filament.
