Answer:
Kepler did and stated that planets move in a elliptical orbit with the sun in the center.
Answer:
32.925 m.
Explanation:
The formula of centripetal acceleration is
a = v²/r ............... Equation 1
Where a = centripetal acceleration, v = linear velocity, r = radius.
make r the subject of the equation.
r = a/v²............. Equation 2
Given: v = 22 m/s,
a = 1.5 times free fall acceleration
Note: Free fall = 9.8 m/s²
Therefore, a = 1.5×9.8 = 14.7 m/s²
Substitute into equation 2
r = 22²/14.7
r = 484/14.7
r = 32.925 m.
Hence the radius of the turn = 32.925 m.
Answer:
I = 12*B (the information about B does not appear in the statement)
Explanation:
The motion of the segment of the circuit, in a constant magnetic field makes that opposite charges inside the segment separate of each other. This generate a induced potential difference at the ends of the segment that is given by the following formula:
(1)
v: speed of the segment = 2.0m/s
B: magnitude of the magnetic field
(2)
The induced current calculated by replacing the result of (2) in the following formula:
(3)
Then, you only have to replace the value of the magnitude of the magnetic field B in (3) to calculate the current.
<span>Velocity is a vector quantity, that's formally defined as the rate of change of position or displacement with time. When stating any vector like the velocity of an object, we talk about direction, as well as magnitude. That's why speed and velocity are different things. Speed is a scalar (a pure number, specified by magnitude, without direction), while velocity is a vector. To put it simply, speed is the magnitude of the velocity. When talking about velocity, we specify it according to some fixed frame of reference and its unit is meters/second. It can be measured in two ways. One is in the form of average velocity, while the other is instantaneous velocity. The formula for the former is as follows.</span>
0.425
BECAUSE 1000g makes 1Kg
so 425g will make 0.425 option a
