You inflate a front tires on your car to 22 psi. Later, you measure your blood pressure,obtaining a reading of 127/61, the readi

Lena [83]

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

A 0.250 kg block attached to a light spring oscillates on a frictionless, horizontal table. The oscillation amplitude is A = 0.1

bulgar [2K]

The spring constant, k will be 18 N/m.The ratio of force to one unit of displaced length is known as the spring constant.

<h3>What is the spring constant?</h3>

Spring constant is defined as the ratio of force per unit displaced length.

Given data;

Mass of block,m=0.250 k

Amplitude,A = 0.125 m

Velocity,V=3.00 m/

Spring constant,K=?

The formula for the spring constant when the spring is oscillate at the given amplitude A:

$\rm K = \frac{V_{max}^2 m}{A} \\\\ K = \frac{3.0 \times 0.250}{0.125} \\\\ K=18 \ N/m$

Hence, the spring constant, k will be 18 N/m
