Answer:
c).
Explanation:
As we know that weight of the automobile is given here
so weight = mass times gravity
now from Newton's law
Answer:
last option is the correct one
Answer:
1/2
Explanation:
The energy stored in a capacitor is given by
where
C is the capacitance
V is the potential difference
Calling the capacitance of capacitor 1 and its potential difference, the energy stored in capacitor 1 is
For capacitor 2, we have:
- The capacitance is half that of capacitor 1:
- The voltage is twice the voltage of capacitor 1:
so the energy stored in capacitor 2 is
So the ratio between the two energies is
The answer is the same because in reflection the things look the same as the image that is appeared
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
