False.
Theories are hypotheses that have been shown to accurately and predictably explain results obtained through repeated experimentation, to the point where the hypothesis can be assumed to be true. Then, such a hypothesis would be considered a theory.
Answer:
Explanation:
Kinetic energy gained by alpha particle
= charge x potential difference
1/2 mv² = 3.2 x 10⁻¹⁹ x 3.45 x 10⁻³
.5 x 6.68 x 10⁻²⁷ V² = 11.04 x 10⁻²²
V² = 3.3 x 10⁵
V = 5.74 x 100
= 574 m / s
Mechanical energy is conserved in respect of A , C and D .
Part B
B , C, are unknown .
The radius of its orbit = 8.27 x 10¹³ m
<h3>Further explanation</h3>
Given
mass Jupiter=1.9 x 10²⁷ kg
T = 16.9 days=1.46 x 10⁶ s
Required
the radius =r
Solution
To hold the moon in its orbit, the gravitational force between two objects (jupiter and moon) will be equal to the centripetal force
G = 6.67 x 10⁻¹¹ N/m²kg²
Input the value :
In large stars because they are too massive
Answer:
Explained below
Explanation:
1) Liquid in glass thermometer: This type of thermometer is used primarily to measure the temperatures from inspection of changes in volume of liquid.
Thermometry substance is mercury or alcohol
2) Gas thermometer: This type is used to measure temperature as a result of changes in gas pressure or volume.
Thermometry substance is Gas.
3) Resistance thermometer: This type is used to measure temperature due to changes in electric resistance.
Thermometry substance is Resistance wire.
4) Thermocouple thermometer: This type is used to measure the temperature due to changes in electrical potential difference occurring between two metal junctions.
Thermometry substance is two wires that are dissimilar.
5) Bimetallic thermometer: This is a type of thermometer that measures temperature by converting temperature into mechanical displacement by making use of Bimetallic strip.
Thermometry substance is two metals that are dissimilar.
