Acceleration = force / mass = 8/10 m/s^2
After 5 s (from the start) velocity = 5 x 8/10= 4 m/s
Answer:
A raised weight.
Water that is behind a dam.
Energy transfer takes place when energy moves from one place to another. Energy can move from one object to another, like when the energy from your moving foot is transferred to a soccer ball, or energy can change from one form to another.
Explanation:
To solve the problem, it is necessary to apply the concepts related to the diffraction given in circular spaces. By definition it is expressed as
Where,
\lambda = Wavelength
d = Optical Diameter
Angular resolution
In turn you can calculate the angle through the diameter and the arc length, that is,
Where,
x = The length of the arc
D = Distance
From known data we know that Jupiter's diameter is,
Replacing we have that,
Re-arrange to find d,
Therefore the minimum diameter of an optical telescope to resolve a Jupiter-sized planet is 0.968Km.
Answer:
58.9 N [W24.8°N]
Explanation:
The vectors are at right angles, so the magnitude of their sum is ...
√(38² +45²) ≈ 58.9 . . . . newtons
The angle Fc makes with Fa can be found using the arctangent:
angle between Fa and Fc = arctan(45/38) ≈ 49.8°
The direction required for the sum of the vectors to be zero is the opposite of [E(49.8° -25°)S], so is [W24.8°N]
The vector that makes the sum zero is 58.9 N [W24.8°N].
