Answer:
B) 100 J
Explanation:
Assuming the distance given is measured along the incline, the vertical change in height is (5 m)(sin 30°) = 2.5 m. Then the change in potential energy is ...
∆PE = mg(∆h) = (4 kg)(10 m/s^2)(2.5 m) = 100 J
Answer:3 seconds
Explanation:
Initial velocity(u)=10m/s
Final velocity(v)=25m/s
Acceleration(a)=5m/s^2
time=(v-u) ➗ a
time=(25-10) ➗ 5
time=15 ➗ 5
time=3
time is 3 seconds
From Ohm's Law, Resistance = (voltage) / (current)
The resistance is <em>233,333 and 1/3</em><em> </em><em>ohms</em>.
It could cause them to catch animal disease
Explanation:
Xenotransplantation refers to the transplantation of organs or tissues between different species. E.g. Chimpanzee organ (liver) being transplanted into a human body would come under the category of xenotransplantation.
Pigs have come up as prospective organ donors since their organs and tissues are more or less to that of human’s. However, there are issues such as-
- Xenotransplantation of pig’s tissue into a human would allow easier passage for all types of zoonotic viruses.
- Moreover, if transgenic pigs are used instead of natural pigs it can lead to virus mutation as per the human body demands thus leading to increased susceptibility to human infection.
Thus, engrafting of pig’s tissue in the human body poses a significant risk for humans of catching a zoonotic (animal) disease.
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons of matter are converted into neutrinos, solar radiation, and roughly 4 x
