SOLUTIONS GRADED A+
◍ What is meant by a geostationary satellite.
Answer: It orbits at the same speed as the Earth rotates, this means it appears
to remain in the same place from on Earth
◍ What are the magnetic metals.
Answer: Fe/Co/Ni and some alloys
◍ What is the period of a wave.
Answer: The time taken for a wave to pass a point
◍ What do stars fuse during main sequence.
Answer: Hydrogen into helium
◍ Velocity is.
Answer: a speed in a given direction
◍ What is the dependant variable in an experiment.
Answer: What we measure
◍ If the objects do not need to be touching for the force to act,.
Answer: the force is a non-contact force.
◍ What happens if two poles are near each other?.
Answer: They exert a force on each other.
◍ What is thinking distance affected by?.
, Answer: Your speed.Your reaction time.
◍ Fluorescence lights.
Answer: energy efficient so there good for when light is needed for long
periods.
◍ What are the two forces when considering magnets?.
Answer: Attractive or repulsive.
◍ Optical fibres work because of.
Answer: reflection, the light rays are bounced back and forth until the reach
the end of the fibre.
◍ Refraction.
Answer: A wave slows down when it enters a different medium and bends
either away or towards the normal line depending on the mediums refractive
index
◍ If the current changes direction.
Answer: it changes the direction of the magnetic field.
◍ White surface.
Answer: Has no pigments so reflects light of any wavelength. Surface looks
white in daylight because daylight is white light.
◍ radiation & absorption (method).
Answer: 1. take 4 boiling tubes, painted matt black, gloss black, white and
silver2. pour hot water into each boiling tube3. measure start temp of tube4.
measure temp of tube every minute5. the tube that cools fastest emits
infrared energy quickest
◍ Name some non-contact forces.
Answer: Magnetic, gravitational, electrostatic
◍ What unit is change in momentum in.
Answer: Kgm/s
◍ What is inertia?.
Answer: This is the tendency to continue in the same state of motion.
,◍ What is drag?.
Answer: The resistance you get in gas or luquid.
◍ Types of transverse waves.
Answer: - P Waves- Water waves- Light waves- All Em waves
◍ Factors effecting thinking distance.
Answer: Speed of car - faster slower timeDrugs and alcohol - slower
timeTiredness - slower timeMedication - slower time
◍ What does Fleming's left-hand rule show?.
Answer: That either the current or the magnetic field is reversed then the
direction of the force will also be reversed.
◍ What is a solenoid with an iron core called?.
Answer: a electromagnet.
◍ What is an isolating transformer for.
Answer: - Separate devices such as razors and tooth brushes from the mains
reducing the risk of a shock
◍ The force always acts at right angles towards.
Answer: the magnetic field of the magnets and the direction of the current in
the wire.
◍ More infrared radiation is given out by.
Answer: hotter objects.
◍ What height does a geostationary satellite orbit at.
Answer: 36,000KM above equator
◍ What is the equation for Elastic potential energy.
Answer: Elastic potential energy = 0.5 x spring constant x extension x
extension Ee = 0.5 x k x e x e
◍ How does a Relay Work.
Answer: - Electromagnet used to allow small current to control a large
current- When switch is closed, electromagnet is magnetised and the arm
, causes the contacts to connect- The causes circuit 2 to be switched on
◍ How did the solar system form (4).
Answer: 4. The heat from the sun evaporates and ice near to it and pushes
light material out. This leaves clumps of rock near to the star
◍ Uses of Radio waves.
Answer: TV broadcasting from TV masts, Local radio station, National and
International Radio, Bluetooth, Wifi
◍ What is the Symbol and unit for Magnetic Flux Density.
Answer: B. Measured in Tesla(T)
◍ What shape is the magnetic field around a current carrying wire.
Answer: Concentric circles
◍ Work Done (J) =.
Answer: Force (N)x Distance (m)
◍ How does a circuit breaker work?.
Answer: When current is too high, switch is pulled to the electromagnet
breaking the circuit
◍ What is the equation to work out the power lost in a cable.
Answer: P=I²RPower=Current²xResistance
◍ Fluorescence is a property of certain chemicals, they.
Answer: absorb UV light and emit visible light, this is done by a layer of
phosphorus.
◍ If something collided to gain mass the.
Answer: momentum would be the same but the velocity would decrease.
◍ acceleration (investigation).
Answer: - newton's second law (acceleration is directly proportional to the
force and inversely proportional to the object's mass)
◍ acceleration (equipment).
Answer: light gate, trolley, pulley, string, four 100g masses, clamp
