A rugby player passes the ball 7.88 m across the field, where it is caught at the same height as it left his hand. (Assume the p
damaskus [11]

Explanation:

Given

Range of ball =7.88 m

Initial speed=13.1 m/s

and we know

Range of Projectile is

R=\frac{u^2sin2\theta }{g}

13.1=\frac{13.1^2\times sin2\theta }{9.8}

7.88\times 9.8=13.1^2\times sin2\theta

sin2\theta =0.4499

2\theta =26.74^{\circ}

\theta =13.37 ^{\circ}

(b)other angle would be complementary of \theta

=90-\theta =76.63 ^{\circ}

Hi,

Newton's Law of Inertia explains this action because the resistance of the seat belt allows the change in its state of motion. So because the change of speed, your body moves forward but is restricted by the seat belt.

Why does salt dissolve in water act as an antifreeze?
aalyn [17]

Answer:

A

Explanation:

An antifreeze is a substance which when added to a liquid reduces the freezing point of the liquid. Hence the solution can only freeze at a lower temperature compared to the solvent. Examples of antifreeze includes salt and propylene glycol. Antifreeze are used in low temperature environments to prevent water from freezing quicky. Hence the answer is A.
