Three Types of Solutions of a System of Linear Equations. There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution. This video shows an example of each type of outcome.
Answer:
Explanation:
1. The gravitational force is related to the mass of each object.
This is true, the gravitational force between the two objects is directly proportional to the product of masses of two objects.
2. The gravitational force on a satellite is less at an altitude of 500 km above the Earth than at an altitude of 1000 km.
It is false, as the gravitational force between two objects is inversely proportional to the square of distance between them. The objects at more height has less gravitational force.
3. The gravitational force between the Earth and a person is constant, no matter how high the person is above the surface of the Earth.
It is false, because as we go on heights the value of acceleration due to gravity decreases.
Mass of cat = 10 lb
1 lb = 0.454 kg
So mass of cat is 4.54 kg
Number of tablets given to cat
Each tablet has 6 mg of drug
Total drug given to cat
Now dose given to cat in mg/kg form
Answer:
R = 1.79*10^6 Ω
C = 2.46*10^-6 F
Explanation:
Given
emf of the source, ε = 120 V
Current passing through the resistor, I = 6.7*10^-5 A
Time constant for the circuit, τ = 4.4 s
From the information above, we can say that RC = 4.4 s
Also, on applying the loop rule, we get
ε - IR = 0
ε = IR
R = ε / I
R = 120 / 6.7*10^-5
R = 1.79*10^6 Ω
Using the first equation, we can thus solve for C
RC = 4.4 s
C = 4.4 / R
C = 4.4 / 1.79*10^6
C = 2.46*10^-6 F
C = 2.46 μF
Therefore, the resistance and capacitance of the capacitor is respectively, 1.79 MΩ and 2.46 μF
<h2>
Answer:When electrons absorb or emit quantized units of energy in the form of photons.</h2>
Explanation:
When a electron is collided with a photon with exactly the same energy it would require to get to any of the farther orbits,electron transition takes place to an orbit depending on the energy of the photon.
When electrons emit exactly the same amount energy that is difference between the current energy level and the new level,then the electron makes a transition to the new level.
