Answer:
newton = SI Unit for force
balanced forces = change in an objects motion
unbalanced forces = no change in an objects motion
net force = combination of all forces acting on an object
Explanation:
Answer:
8m
Explanation:
The magnitude m of a vector (x, y) is given by
m = -------------------------(i)
where;
x and y are the x- and y- components of the vector.
From the question;
m = 10m
x = 6m
Substitute these values into equation (i) as follows;
10 =
Solve for y;
<em>Find the square of both sides</em>
10² = 6² + y²
100 = 36 + y²
y² = 100 - 36
y² = 64
y = √64
y = 8
Therefore, the y-component of the position vector is 8m
Answer:
123.2 m/s after 28s
Explanation:
Vi= 0 m/s
a= 4.4 m/s^2
t=28s
Vf after 28s
To find Vf use your kinematics formula Vf=Vi+at
Vi is Zero so it gets removed and the equation becomes
Vf=at
Simply Plug and Solve
Vf= 4.4(28)
Vf=123.2 m/s after 28s
<u>Answer:</u>
The path followed = sun to sky to balloon to eyes
<u>Explanation :</u>
The sun gives light which reaches the sky i.e atmosphere of the earth and gets scattered , after scattering the light from the sky touches the balloon and thus coming from various directions after scattering, it touches the balloon at various points and gets reflected and then reaches our eyes and thus makes the hot air balloon visible to us.
Hence,this is the path followed by the light in order for us to see the brightly colored hot air balloon in a sunny sky and it's individual colors.
They would hit the ground at the same time. No matter the weight laws of physics.
