Answer:
photosynthesis is the process by which plant prepares food using carbondioxide and water in the presence of sunlight
The tool used to gauge atmospheric pressure is a barometer. Concerning the device used to gauge air pressure, we have been questioned.
- Mercury is used in barometers. A reservoir of mercury is compressed by atmospheric pressure, and depending on the force of the air, the mercury is propelled up into the tube to a specific height. A straightforward barometer consists of a long glass tube that is filled with mercury and is closed at one end and open at the other. As most cases, the air pressure is expressed in mm Hg.
- By delivering quick, precise information on a range of metrics, Radiometer's products and solutions aid in the diagnosis and treatment of critically ill hospital patients.
- A hygrometer is a device that gauges the moisture content of soil, air, or restricted spaces. Measurements of other quantities, such as temperature, pressure, mass, or a mechanical or electrical change in a substance as moisture is absorbed, are typically used as the basis for humidity measurement systems.
- Voltmeters are used to measure voltages, while thermometers measure temperature.

(a) 0.0068 Wb
Since the plane of the coil is perpendicular to the magnetic field, the magnetic flux through the coil is given by
where
N = 200 is the number of loops in the coil
B is the magnetic field intensity
is the area of the coil
At the beginning, we have
so the initial magnetic flux is
at the end, we have
so the final magnetic flux is
So the magnitude of the change in the external magnetic flux through the coil is
(b) 0.567 V
The magnitude of the average voltage (emf) induced in the coil is given by Faraday-Newmann law
where
is the variation of magnetic flux
is the time interval
Substituting into the formula, we find
(c) 0.142 A
The average current in the coil can be found by using Ohm's law:
where
I is the current
V is the voltage
R is the resistance
Here we have:
V = 0.567 V (induced voltage)
(resistance of the coil)
Solving for I, we find
Answer:
4km
Explanation:
Distance=speed x time
Knowing this we know the time and speed
so it is 8 x .5= D
And 8 x .5 =4
