Answer:
False
Explanation:
It is not necessary, that when the initial speed of the object is zero then it must be at origin.
It may be the object starts motion from the left of origin.
Answer:5m
Explanation:a=-10m/s (since it moved upwards against gravity)
V=0
U=10m/s
v2=u2+2as
0= 100-20s
20s=100
s=5m
Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]
Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35 [ tan 35 = 0.70 ]
In short, Your Answer would be 35 degrees
Hope this helps!
Gravity
Explanation:
Johanna's table:
Circular motion Centripetal force
space station in orbit X
a child in a swing
a ball on a string
The type of centripetal force at work in a space station in orbit is the force of gravity.
The force of gravity is constantly pulling and attractive all objects and bodies to its center.
This force is directed towards the center of the orbit of the earth and it is a centripetal force
- Gravity attracts any object that has mass.
- The mass of the satellite and the earth keeps it in orbit and prevents it from moving out of orbit.
- The more the mass the more the gravitational attraction.

Answer:
Jedge = 0.076A/cm^2
Explanation:
If you want to know what is Jedge is convenient to use an integral. The total density current is given by:
(1)
But also, we have that the total current is
where we have used that 5mm=5*10^{-3}m.
By replacing (1) we obtain:
