Answer: 240 mL

Explanation:

(20 kPa)(300 mL) = (25 kPa)V2

V2 = 240 mL

Or my way which was

300 mL / 25 kPa =12

12(5)=60

300-60=240mL

Answer:

The correct answer is -

FALSIFIABLE:

Aloe vera gel can heal wounds by boosting cell renewal.

Drinking aloe juice can reduce the risk of lung cancer.

NON-FALSIFIABLE:

Aloe vera gel is the best natural skin moisturizer.

Aloe vera juice tastes better than carrot juice.

Explanation:

Falsifiable is the ability or chances of any hypothesis, claim or statement to be proved wrong. In such a hypothesis, it is possible to carry an experimental observation that disproves the idea in claim or question.

In the given examples

Aloe vera gel can heal wounds by boosting cell renewal.

Drinking aloe juice can reduce the risk of lung cancer.

There is no observation in the favor of the claim so there more likely to be falsifiable whereas, Aloe vera gel is the best natural skin moisturizer.

Aloe vera juice tastes better than carrot juice are more non-falsifiable as these are based on personal choice or experimental observation.

Find the horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40m/s​
vfiekz [6]

To Find :

The horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40 m/s​.

Solution :

The horizontal range of a projectile is given by :

R = \dfrac{u^2 sin 2\theta}{g} ( Here, g is acceleration due to gravity = 10 m/s² )

Putting all value in above equation :

R = \dfrac{40^2 \times sin (2 \times 15)}{10} \ m\\\\R = \dfrac{1600 \times 1}{2\times 10} \ m\\\\R = 80 \ m

Therefore, the horizontal range of projectile is 80 m.
