Answer:
A)
B)
Explanation:
<u>Given:</u>
Length of the room
Width of the room
A) Let A be the area of the room
B)We will calculate uncertainty in each dimension
%uncertainty in length
%uncertainty in width =
The uncertainty in area will be sum of uncertainty in length and width
%uncertainty in Area= %uncertainty in length + %uncertainty in width
%uncertainty in Area
%uncertainty in Area=0.0106
Uncertainty in Area
There Area is
A motor uses an electromagnet to convert electrical energy into mechanical energy.
Answer 1) : Hydrosphere.
Explanation : The largest sphere on the planet is hydrosphere, which is the combined mass of water found on a planet, available under, and above the surface of a planet, minor planet or natural satellite. It has been estimated that there are 1,386 million cubic kilometers of water on Earth. So, this is the largest sphere on a planet if you are traveling on Earth.
Answer 2) The other parts of the sphere are geosphere, atmosphere and biosphere.
Explanation : Geosphere - This sphere includes all the stuff that make up the crust and the core of the earth. It includes everything natural and lifeless that make up the surface of the earth. Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans.
Atmosphere - The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity.
Biosphere - It is also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system, and largely self-regulating.
Answer:
0.4cm
Explanation:
First, you calculate the dis acceleration of the electron generated by the potential difference between the plates:
(1)
q: charge of the electron = 1.6*10^-19 C
V: potential difference between plates = 100V
m: mass of the electron
d: distance between parallel plates = 1cm = 0.01m
by replacing the values of the parameters you obtain:
you use this value in the following kinematic equation:
(2)
v: final velocity = 0m/s (until the electron stops)
from the equation (2) you calculate x, the distance traveled by the electron. But before you calculate the initial velocity of the electron by using the following equation:
Next, you replace vo in (2) to obtain x:
Then, the electron travels 0.1cm from the middle of the region between the parallel plates, hence, the distance between the electron and the negatve plate is:
0.5cm-0.1cm=0.4cm
If their average velocity is 55 mph Northwest, they won't arrive in Santa Fe.
First of all, the straight-line distance from Houston to Santa Fe is only 740 miles. And if the headed out from Houston going northwest and maintained that heading, then they passed about 135 miles north of Santa Fe.
Let's just work with SPEED, OK ?
If they drove 881 miles at an average speed of 55 mi/hr, then
the trip took them
(881 mi) x (hr / 55 mi) = 16.018 hours (16 hrs 1 min)
