Should the resistance of an ammeter low or high ?give reason
Answers
Answer:
The resistance of an ammeter should be low. This is because an ammeter is connected in series with the circuit for the measurement of electric current. In case, its resistance is high, then some amount of current may lost in heating it leading to the inaccurate reading. An ideal ammeter is one which has zero resistance.

Answers
Answer:
Explanation:
Given parameters:
Weight of object = 49N
Force applied = 12N
Unknown:
Acceleration of object = ?
Solution:
The acceleration of the object is found by dividing the force by the weight;
Acceleration = [tex]\frac{12}{49}[/tex] = 0.25m/s²

The problem here deals with relative dating of fossils in a stratigraphic column.
To solve this problem, we apply one of the rules of interpreting a session which is the principle of fossil and fauna succession:
"fossils and fauna in a geologic sequence succeed one another in a predictable way".
The oldest fossil is found in the oldest bed usually at the bottom of the sequence.
The youngest fossil is found at the top of the beds.
1. Oldest organism in the sequence;
Trilobite
2. Organism in the youngest layer;
Fern
3. Older organism between Crinoid and Ammonite;
Ammonite
The ammonite is below the crinoid in the sequence.

What is the voltage drop across the 20 resistor?
10.00
120.0 V
20.0 2.
www
30.02
Answers
The voltage drop across the 20 Ohm resistor is 40V.
To determine the answer, we need to know about the current flowing through the resistor.
What is the total resistance of the circuit?As the three resistors are connected in series, so the resultant resistance is
10 Ohmv+ 20 Ohm + 30 Ohm = 60 Ohm
What is the current flowing through the resistors?As these resistors are connected in series, so the amount of current flowing through each resistor is equal.According to Ohm's law, current = voltage/resistanceCurrent= 120/60 = 2 A
What is the voltage across the 20 Ohm resistor?According to Ohm's law, voltage across the 20 Ohm resistor
= current×resistance
= 2×20
= 40volt
Thus, we can conclude that the voltage across the 20 Ohm resistor is 40V.

Which pair of concurrent forces could produce a resultant force having a magnitude of 10. Newtons?
Answers
The pair of concurrent forces will be of 5 N to make the magnitude of net force as 10 N.
Given data:
The magnitude of resultant force is, [tex]F_{net}=10 \;\rm N[/tex].
The given problem is based on the concept of concurrent forces which says that, If the forces applied to a body are such that their lines of action meet at a single point, then they are called concurrent forces.
Now to obtain the value of concurrent forces, let us consider the forces F and F' to be acting along a linear direction. Such that the net force is given as,
[tex]F_{net}=F+F'[/tex]
Then for 10 N of net force, the pair of concurrent force is,
[tex]10=F+F'\\\\10=5+5\\\\10=10[/tex]
Thus, we conclude that the pair of concurrent forces will be of 5 N to make the magnitude of net force as 10 N.

What is the mass of 0.48 mol of cadmium, cd in grams.
Answers
Answer:
53.95g
Explanation:
Given parameters:
Number of moles = 0.48mol
Unknown:
Mass of cadmium = ?
Solution:
The number of moles, molar mass and mass of the atom is related by the expression;
Mass of Cd = number of moles x molar mass
Molar mass of Cd = 112.4g/mol
Now;
Mass of Cd = 0.48 x 112.4 = 53.95g
