When a person meets a hot object without thinking about it, the heat stimulates temperature and danger receptors in the skin, resulting in a sensory impulse that passes to the central nervous system. After that, the sensory neuron forms synapses with interneurons, which then connect to motor neurons.
I’m assuming the cannon ball is being shot directly horizontally. If there’s an angle, this answer will be wrong. But either way, you want to use Newton’s Second Law of motion.
F = ma, you could change this to a = F/m to get a better understanding of the equation. Acceleration and force are directly proportional. The mass is inversely proportional to acceleration. This means the net force will be in the same direction as the acceleration.
Alright back to the problem:
F = 4kg*110m/s^2
F = 440N
Answer:
See the answer below
Explanation:
After routinely cleaning the microscope and ensuring that all the parts are working fine, Dylan would have to <u>place the slide on the stage of the microscope, switch on the light source, and adjust the diaphragm of the condenser to ensure that adequate light gets to the slide on the stage</u>.
Thereafter, Dylan would need to<u> turn the revolving nosepiece in order to shift to the lowest objective of the microscope</u> assuming it is not already in place. Then,<u> the slide on the stage is brought into focus (by viewing through the eyepiece/ocular) by using the coarse/fine adjustment knob to bring the stage up/down.</u>
Once the slide is brought into clear focus, <u>the revolving nosepiece is then turned to switch the x20 objective. </u>Generally, at higher objectives, the coarse adjustment knob is rarely needed and the fine adjustment knob is solely used instead to bring the slide back into focus. Thus, Dylan can see the cells of the onion at the desired objective.
The answer is A. (delta).
