Answer:
a) 1.5 × 10² kPa
b) 16.9/8.1
Explanation:
a) The pressure of the front tires is 22 psi. The appropriate conversion factor is 1 psi = 6.89 kPa. The pressure of the tires in kPa is:
22 psi × (6.89 kPa / 1 psi) = 1.5 × 10² kPa
b) Regarding the blood pressure, the minimun reading is 61 mmHg and the maximum reading is 127 mmHg. The appropriate conversion factor is 1 kPa = 7.50 mmHg. The blood pressure in kPa is:
61 mmHg × (1 kPa / 7.50 mmHg) = 8.1 kPa
127 mmHg × (1 kPa / 7.50 mmHg) = 16.9 kPa
Answer:
Part a)
Part b)
Magnitude of the force is given as
Part c)
As we know that Y component of the force is negative so here the force is directed below the X axis
Explanation:
Part a)
Adrienne apply the force of 20 N along +X direction and Jim apply force of 40 N at 53 degree above negative X axis
so we will have
now let say the force exerted by Luis is F such that sum of all forces must be zero
now we have
so we have
Part b)
Magnitude of the force is given as
Part c)
As we know that Y component of the force is negative so here the force is directed below the X axis
So here we have
Answer:
The diameter of the bull-wheel is 3.82
Explanation:
Given that,
Velocity = 2.0 m/s
Angular velocity = 10 rev/m
We need to calculate the diameter of bull-wheel
Using formula of angular velocity
Put the value into the formula
The diameter of the bull-wheel
Hence, The diameter of the bull-wheel is 3.82 m.
