Answer:
a) y = 162.6 m
, b) R = 928.64 m
Explanation:
We will solve this exercise using projectile launch kinematics, as the initial velocities and angle are equal on the planet and the Earth, let's look for the gravedd coinage of the planet
Earth
R = v₀² sin 2θ / g
R g = v₀² sin 2θ
In the planet
4.8 R = v₀² sin 2θ / 
4.8 R = v₀² sin 2θ
4.8 R = R g
= g / 4.8
= 9.8 / 4.8
= 2.04 m / s²
Now we can answer the questions
a) The maximum height
Vy² = 
² - 2 g y
For ymax the vertical speed is zero ( 
= 0)
sin θ = / 
= sinθ
= 44.9 sin 35
= 25.75 m/s
y = ²/2
y = 25.75² / (2 2.04)
y = 162.6 m
b) the scope
R = v₀² sin 2θ /
R = 44.9² sin 2 35 / 2.04
R = 928.64 m
Answer: Hello, I dont know if this gives much information but here. Glass comes in the insulator class of material which means it is a poor conductor of heat. when you pour a very hot liquid into a thick tumbler what happens is, the surface of glass that comes in contact with the hot liquid heats up and expands as per its coefficient of thermal expansion, while the outer layer still remain cold and does not expands (because glass is a poor conductor and does not carry heat quickly). This leads to development of thermal stresses which eventually causes cracking.
Explanation:
from rest
dist = 1/2 accn timextime
=1/2 3.2 32.8x32.8
about 1.6x900 m/s ... 1350m
Answer:
Transformers use “electrical steel” alloys. ... From 1% to 6.5% silicon is added, as well as a small amount (up to 0.5%) of manganese and aluminum to reduce brittleness in alloys with higher percentages of silicon. Electrical steels are formulated and processed to have low hysteresis and eddy-current losses.
Explanation:
The eddy currents consume energy and heat the iron core. The designers of the electrical machines and transformers laminate the core with thin sheets of iron coated with a thin oxide layer.
Answer:
A change has occurred in a nucleus
