Answer:
We can infer that the charge on object B is Neutrally charged.
Explanation:
From the above we can assume object B is neutral and was charged by induction.
During the process of charging by conduction, both objects A and B acquire the same type of charge after contact.
It follows the rule that says that if a positively charged object A is used to charge a neutral object B, then both objects A & B become charged positively charged.

Answer:
184.3g
Explanation:
Given parameters:
Volume of acid = 42.5L
Unknown:
Mass of acid = ?
Solution:
We have to assume that this measurement was taken at rtp;
At rtp;
1 mole of a substance occupies a volume of 22.4L
Therefore,
42.5L of H₂SO₄ will have moles = 1.9moles
To find the mass;
Mass = number of moles x molar mass
Molar mass of H₂SO₄ = 2(1) + 32 + 4(16) = 97g/mol
Mass = 1.9 x 97 = 184.3g
Answer:
Infrared thermography
Explanation:
Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. ... We call our equipment as infrared thermography considering such generalization of the terminology.
