If the caffeine concentration in a particular brand of soda is 2.97 mg/oz, 2.97 mg/oz, drinking how many cans of soda would be l

Ray Of Light [21]

Explanation:

The given data is as follows.

Concentration of caffeine = 2.97 mg/oz

Number of oz in a can = 12 oz

Therefore, the concentration of caffeine in one can is calculated as follows.

= $(12 \times 2.97)$ mg

= 35.64 mg

= $35.64 \times 10^{-3} g$

Since, it is given that lethal dose is 10.0 g. Hence, number of cans are calculated as follows.

No. of cans = $\frac{\text{Lethal dose}}{\text{concentration in one can}}$

= $\frac{10 g}{35.64 \times 10^{-3} g}$

= 280.58

= 281 (approx)

Thus, we can conclude that 281 cans of soda would be lethal.

A 1000-kg car is driving toward the north along a straight horizontal road at a speed of 20.0 m/s. The driver applies the brakes

Nitella [24]

Answer:

The value of F= - 830 N

Since the force is negative, it implies direction of the force applied was due south.

Explanation:

Given data:

Mass = 1000-kg

Distance, d = 240 m

Initial velocity, v1 = 20.0 m/s

Final velocity, v2 = 0 (since the car came to rest after brake was applied)

v2²= v1² + 2ad (using one of the equation of motion)

0= 20² + (2 x a x 240)

0= 400 + 480 a

a = - 400/480

a = - 0.83 m/s²

Then, imputing the value of a into

F = ma

F = 1000 kg x ( - 0.83 m/s²)

F= - 830 N

The car was driving toward the north, and since the force is negative, it implies direction of the force applied was due south.
