Answer:
Explanation:
Given,
Mass of the steel = 19 g
height reached, h = 1.35 m
angle, θ = 35°
when the ball is projected vertically with initial velocity v.
Maximum height reached is equal to,
initial velocity,
v = 5.14 m/s
Hence , the maximum velocity is equal to 5.14 m/s
For projectile motion horizontal distance is given by
the horizontal distance travel by the ball is equal to
Answer:
Metals are lustrous, malleable, ductile, good conductors of heat and electricity.
Luster: Metals are shiny when cut, scratched, or polished.
Conductivity: Metals are excellent conductors of electricity and heat.
Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped.
Ductility allows structures to bend and deform to some extent without rupturing.
Luster: Metals have the quality of reflecting light from its surface and can be polished e.g., gold, silver and copper
Explanation:
Answer:
C-D
Explanation:
As you can see from the graph, the distance from A to B was from 0 m to 6 m in a duration of 3 seconds.
Divide 6 meters by 3 seconds to find the speed:
6 ÷ 3 = 2 m/s
B-C is not moving due to a straight line as said in the graph, so speed is
0 m/s.
There is also C-D since the car traveled from a distance of 9 meters
(6 -(-3) = 9) in 3 seconds too. (NOTE: The graph line going down does not mean it is slowing down, but rather going to a certain distance like going backwards)
Divide 9 meters by 3 seconds to get the speed:
9 ÷ 3 = 3 m/s
Between A-B, B-C, and C-D, C-D has the fastest speed recorded with 3 m/s.
A-D does not count here as the line has no connection between point A and point D.

Blue would bend the most, since it has a greater refractive index. It has more energy and a shorter wavelength, so it slows.
