The answer is 7 (its like the only question thats easy so far lol)
Hi!
The correct option would be C.
<h3>Explanation:</h3>
Scientific method is the protocol in an experiment for a hypothesis that involves testing, measurement, observation and necessary modification of hypothesis during the course of the experiment. There are several manners and experiments that can be tested for the hypothesis, and plenty of ways to design an experiment.
Scientific experiments can be very tricky to design, owing to the numerous parameters and variables that need to be accounted for. Of course, there are some relatively simple experiments. Creativity is needed for all branches of science, because each field presents obstacles in discovery, and creativity allows for us to devise ways around those obstacles. Science has always tested humans ability to think outside the box and question their surroundings, and creativity has been the driving force.
Hope this helps!
An electric toaster takes in electrical energy from the power outlet and converts it into heat<span>, very efficiently. If you want your toast to cook quickly, you need a toaster that radiates as much </span>heat<span> as possible each second onto your bread.</span>
The current in the circuit =5 A
Explanation:
Voltage = 60 V
resistance= 12 ohm
using ohm's law V=i R
60= i (12)
i=60/12
i=5 A
Thus the current flowing in the circuit = 5 A
Answer:
a2 = 2.5 m/s2
Explanation:
F1 = m1 a1 We use the same force so F1 = F2
= 5kg × 15m/s2 F2 = m2 a2
= 75N a2 is required
a2 = F2 / m2
= 75N / 30 kg
= 2.5 m/s2
