Answer:
The magnitude of the magnetic field is 1.01T and its direction is in the negative x direction
Explanation:
In order to calculate the magnitude and direction of the magnetic field, you take into account the following equation for the magnetic force on the proton:
(1)
v: speed of the proton = 9.9*10^5 m/s
q: charge of the proton = 1.6*10^-19C
B: magnetic field = ?
FB: magnetic force on the proton = 1.6*10^-13N
When the proton travels in the positive y direction (^j), you have that the proton experiences a force in the positive z direction (+^k). To obtain this direction of the magnetic force on the proton, it is necessary that the magnetic field points in the negative x direction, in fact, you have:
^j X (-^i) = -(-^k)=^k
To obtain the magnitude of the magnetic field you use:
The magnitude of the magnetic field is 1.01T and its direction is in the negative x direction
Answer:
speed and acceleration of the turbine V = 80.24 m/s and a = 109.1 m/s²
Explanation:
The wind turbine describes a circular motion, with constant angular velocity, we can find the speed with the equation
V = x / t
Where x is the distance traveled which is the length of the circle (X = 2πr) and time is the time in a revolution, which in this case is called the period
t = 60/13
t = 4.62 s
x = 2 p1 59
x = 370.71 m
V = 370.1 / 4.62
V = 80.24 m / s
The centripetal acceleration is given by the equation
a = V² / r
a = 80.24²/59
a = 109.1 m / s²
The second part of the exercise seems totally independent
The dog r = 16cm with a speed of 2.5 m/s, ask us the centripetal force
F = m a
F = m (v² / r)
m = 10 mg (1g / 1000mg) 1 Kg / 1000 g) = 1 10⁻⁵ Kg
r = 16 cm (1m / 100cm) = 16 10⁻² m
F = 1 10⁻⁵ 2.5²/16 10⁻²
F = 3.91 10⁻² N
Let's calculate the relationship between the force and the weight of the drop
F / W = 3.91 10⁻² (1 10⁻⁵ 9.8)
F / W = 3.99 10
²
See that the force of the shake is approximately 400 times greater than the weight of the drop
Answer:
Explanation:
While the satellite is in the space vehicle, it has the next potential energy
where G is the gravitational constant
m is the satellite's mass in kilograms
Me is the earth's mass
r is the orbit's radius from to the earth's center in meters
The additional energy required is the difference between this energy and the energy that the satellite would have in an orbit with an altitude of 22000 mi
Then
The measurement of the required quantities are carried out using the
standard tools.
<h3>Measurement</h3>
Measurement involves measuring the quantity an object or a body has.
These are done by the standard tools used for different types of quantities.
Examples include:
- Tape rule which is used to measure the length
- Beam balance which is used to measure the mass etc.
They normally have standard readings which helps to get accurate results
which is reproducible in all parts of the world.
