Hello!
Pseudoscience in a sentence is "A pseudoscience is set of ideas based on theories put forth as scientific when they are not scientific."
Answer:
142.296 Nm.
Explanation:
Torque: This is the force that tend to cause a body to rotate or twist. The S.I unit of torque is Nm.
From the question,
T = F×r.................... Equation 1
Where T = Torque, F = Force, r = radius of the circle.
Note: F is the weight of the bicyclist.
Then,
F = W = mg............... Equation 2
Substitute equation 2 into equation 1
T = mgr................... Equation 3
Given: m = 88 kg, g = 9.8 m/s², r = 0.33/2 m
T = 88(9.8)(0.33)/2
T = 142.296 Nm.
The answer is B - Current Y has a greater potential difference, and the charges flow at a slower rate.
I just took the quiz
Answer:
D
Explanation:
Speed = distance / time
her time for the first journey = 20 miles / 60 miles/hr = 1/3 hr
her time for second part of the journey = her remaining distance / her speed = (80 - 20) miles / 30 miles/hr = 60 miles / 30 miles/hr = 2 hrs
total time spend by her = 2 hr+ 1/3 hr = 2 1/3 hrs
her traveling the distance at 40 miles per hour = 80 miles / 40 miles /hr = 2 hrs
the time less she would drive if she drive the entire distance at 40 miles/hr = 2 1/3 hrs - 2 hrs = 1/3 hr
