BMAT Exam Questions and Answers(Latest update 2024) 200+ Questions
What factors affect the magnitude of an induced voltage? - Correct Answer
✅- the rate at which the wire cuts the magnetic field lines
-- e.g.the magnet spins at a greater rate meaning more field lines are cut per
second
-- a stronger magnet is used meaning there are more magnetic field lines
- the rate at which the magnetic filed through a conductor changes
-- e.g. the ac frequency in coil A is increased
-- e.g. the ac amplitude in coil A is increased
- number of turns in the coil is increased
nano- - Correct Answer ✅10⁻⁹
micro- - Correct Answer ✅10⁻⁶ (µ)
milli- - Correct Answer ✅10⁻³
centi- - Correct Answer ✅10⁻²
deci- - Correct Answer ✅10-¹
kilo- - Correct Answer ✅1000 or 10³
mega- - Correct Answer ✅10⁶

✅antibody production and phagocytis
What is the role of platelets in the blood? - Correct Answer ✅Blood clotting
What are the roles of plasma in the blood? - Correct Answer ✅- transport
of blood components and other dissolved substances and other dissolved
substances including hormones, antibodies, urea and carbon dioxide
- distribution of heat

able to form stable ions in different oxidation states b. they often form
coloured compoundsc. they are often used as catalysts (as ions or atoms)
Test for oxygen - Correct Answer ✅Relights a glowing splint

Flame test - Cu - Correct Answer ✅green
How do you test for the presence of water? - Correct Answer ✅- Add
anhydrous copper(II) sulfate
- Results in a colour change from white to blue
How can two insulators become charged? - Correct Answer ✅by friction
- when two insulators move relative to each other, they can become
electrically charged
- one will become positively charged and the other negatively charged
- e.g plastic rubbed by a duster, hair combed, fuel moving through a pipe
and an aeroplane moving through the air
Can conductors become charged by friction? - Correct Answer ✅Yes, if
they are insulated from their surroundings, otherwise the charge will leak
away
How can a neutral object become charged by induction? - Correct Answer
✅Much like when a unmagnetised piece of iron becomes magnetised when
it moves near to a magnet, a neutral object can become charged when
placed near to a charged object
How can an object charged by induction become permanently charged? -
Correct Answer ✅If it is momentarily earthed, allowing the charge at one
end to leak away
How does an object become charged in terms of particles? - Correct
Answer ✅- when two objects are rubbed together, there is a transfer of
electrons
, BMAT Exam Questions and Answers
(Latest update 2024) 200+ Questions
- if an object gains electrons, it becomes negatively charged
- if an object loses electrons, it becomes positively charged
ELECTROSTATIC CHARGE IS ALWAYS CAUSED BY ELECTRONS
- which way the electrons move and so how each material becomes charged
depends on how strongly the atoms attract electrons
What are uses of electrostatic charging by friction? - Correct Answer ✅-
photocopying
- laser printing
- electrostatic air cleaning
What are risks of electrostatic charging by friction? - Correct Answer ✅-
can result in sparks
-- occur when air between two objects becomes ionised and starts
conducting
- two charged objects with air between them can discharge a spark when the
charge becomes large enough or the distance between them becomes small
enough
How can the risks associated with electrostatic charging by friction be
eliminated? - Correct Answer ✅earthing
- by both being connected by a wire or one object being connected by a wire
to the earth
-- means that electrostatic charging cannot take place so the risk is averted
wires crossing - Correct Answer ✅
wires connected - Correct Answer ✅
