If the coefficient of static friction between your friend and the car seat is 0.500 and you keep driving at a constant speed of

Rasek [7]

Answer:

90m

Explanation:

Let g = 9.8 m/s2. The friction is the product of normal force and its coefficient, and normal force is equal to gravity

$F_f = \mu N = \mu mg$

The acceleration caused by friction, according to Newton's 2nd law:

$a_f = F_f / m = \mu g = 0.5 * 9.8 = 4.9 m/s^2$

For the friend to slide over, then the centripetal acceleration must be equal to friction acceleration.

Since you are driving at a constant speed of 21 m/s, then your maximum radius of curvature can be calculated using the following formula:

$a_c = a_f = v^2/r = 4.9$

$r = v^2/4.9 = 21^2/4.9 = 90 m$

Choose all of the true statements regarding the relationship between voltage, resistance, and current. Current is measured in am

AveGali [126]

-- Current is measured in amps. (You can use any symbol you want to represent current, but the most common one is " I ", not "Δ".)

-- The relationship between current, voltage, and resistance is mathematically defined by Ohm's Law.

-- Current is the flow of electrons through a circuit.

-- (Ohm's Law is NOT mathematically represented by the equation V=I/R.) It should be V = I · R .

(When solving for Resistance in a circuit and both voltage and current are known values, the equation I =V*R is not true, and not the way to solve it.) If the resistance is what you're looking for, then the equation to use is R = V / I .

-- If the voltage in a circuit is increased, the current will also increase.
