The weight of the object is if its mass is 10 kg.
Further Explanation:
Weight of any substance is related to the force that acts on it. This force can either be due to gravity or by the reaction force. Most of the time, weight is defined as the force experienced by an object due to gravity and is the product of mass and acceleration due to gravity. It is denoted by W. Since weight is a force, its units are similar to that of force. Its SI unit is Newton (N) or kilogram meter per second .
The formula to calculate the weight of an object is as follows:
...... (1)
Here,
W is the weight of the object.
m is the mass of the object.
g is the acceleration due to gravity.
The mass of the object is 10 kg.
The acceleration due to gravity is .
Substitute these values in equation (1).
Since is equal to 1 N, the weight of the object can also be written as 98 N.

In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.
The average pea weighs between 0.1 and 0.36 grams.
If we take the lower value (0.1 g/pea), the number of peas in 454 g is:
If we take the higher value (0.36 g/pea), the number of peas in 454 g is:
In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.

When nitrous acid (HNO₂) dissociates in water (H₂O), the reaction that best captures this process is:
HNO₂ (aq.) + H₂O ↔ H₃O⁺ (aq.) + NO₂⁻ (aq.)
How does one know about HNO₂?
Is HNO₂ a basic or an acid?
Acidity is assigned to nitrous acid (HNO₂). Once dissolved in water, it gives out H+ ions. Acid is a chemical that produces H+ ions in a water-based solution or gives the protons to other molecules.
Thus, HNO₂ is acid because it causes a mixture of water to contain H+ ions. In a 10 mM concentration, it possesses a pH of 2.67.

Answer : The 'Ag' is produced at the cathode electrode and 'Cu' is produced at anode electrode under standard conditions.
Explanation :
Galvanic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the voltaic cell or electrochemical cell.
In the galvanic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.
We are taking the value of standard reduction potential form the standard table.
In this cell, the component that has lower standard reduction potential gets oxidized and that is added to the anode electrode. The second forms the cathode electrode.
The balanced two-half reactions will be,
Oxidation half reaction (Anode) :
Reduction half reaction (Cathode) :
Thus the overall reaction will be,
From this we conclude that, 'Ag' is produced at the cathode electrode and 'Cu' is produced at anode electrode under standard conditions.
Hence, the 'Ag' is produced at the cathode electrode and 'Cu' is produced at anode electrode under standard conditions.
