A graduated cylinder measures the volume of a liquid.
A stopwatch measures the amount of time that elapses.
A scale measures the mass of objects.
A thermometer measures the temperature of any object.
Because we are measuring rain, a liquid, we would want to use a tool that would allow us to collect the rain for measuring. Therefore, the tool e would use to measure the amount of rainfall would be A. a graduated cylinder.
Answer:
D. Freezing?
Explanation:
Get water, put it in the freezer, turns into ice after a few hours.
Answer:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
Explanation:
6). the presence of caffeine on the worm's skin
7). the worm's heart-rate
8). "Dripping caffeine on a worm's skin causes the worm's heart to beat faster."
(Note: The things she observed suggest but do not PROVE that this hypothesis is true.)
Answer:
The reading on the ammeter A₁ , should be 2 Amp.
Explanation:
Given circuit shows all the bulbs are connected in parallel and ammeter A(T) at the source reads 6 Amp.
So, as the bulbs are in parallel connection, the current gets divided equal to each bulb.
so, the reading on the ammeter A₁ , should be 2 Amp.
But it will show 6 Amp, which is three times of the required value(2 amp).
This is because there was a mistake while making the circuit connections.
Instead of making connections as given circuit, the connections were made different as uploaded circuit.
Instead of connecting ammeter A₁ to only one bulb, it is connected to all the bulbs.
To correct this, remove the wire connecting ammeter and the second bulb.
And connect the second bulb directly to the switch.
