Elastic is most likely to experience it
ANSWER:
a)Angle = 79°
b)Resultant vector = 10.2m/s
a)Use the pythagoras trigonometry ratios to obtain the angle..,
Vertical(opposite) = 10
Horizontal(adjacent) = 2
tan theta = 10/2...,where theta is representing the angle.
;theta = 79°
b) Resultant vector(R)...we use the pythagoras to calculate it,
Where our resultant vector is the hypothenus...,
R^2 = 10^2 + 2^2
R^2 = 104
Hence,
;Resultant vector = square root of 104
= 10.2 m/s
Answer: Erosion or water level rising
Explanation: Erosion happens when water goes against a rock and breaks it down little by little so these mountains may have once been above water but became eroded. Also, people might’ve added so much pollution into the ocean that the water level rose or there was an increase in the population of large animals. Sorry for my very long answer lol
Answer:
Chidera is the stronger individual pushing the box with a net force of 5N to the left.
Explanation:
Chidera is using more force meaning they are stronger and the net force is 5N because when you plug in the equation
F1 = 30 + F2 = -25 = 5N
you get 5N
The triboelectric effect happens; negatively charged electrons transfer from the rod to the paper, making the rod slightly positive charged.
