Answer:

6 V

Explanation:

In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:

V=RI

where

V is the voltage

R is the resistance

I is the current

In this circuit, we have

R=12.0\Omega is the resistance

I = 0.500 A

so we can find the voltage of the battery by using Ohm's law:

V=(12.0 \Omega)(0.500 A)=6 V

A burglar attempts to drag a 108 kg metal safe across a polished wood floor Assume that the coefficient of static friction is 0.
V125BC [204]

Answer:

2.00 m/s²

Explanation:

Given

The Mass of the metal safe, M = 108kg

Pushing force applied by the burglar,  F = 534 N

Co-efficient of kinetic friction, \mu_k = 0.3

Now,

The force against the kinetic friction is given as:

f = \mu_k N = u_k Mg

Where,

N = Normal reaction

g= acceleration due to the gravity

Substituting the values in the above equation, we get

f = 0.3\times108\times9.8

or

f = 317.52N

Now, the net force on to the metal safe is

F_{Net}= F-f

Substituting the values in the equation we get

 F_{Net}= 534N-317.52N

or

F_{Net}= 216.48

also,

 

F_{Net}= M\timesacceleration of the safe

Therefore, the acceleration of the metal safe will be

acceleration of the safe=\frac{F_{Net}}{M}

or

 acceleration of the safe=\frac{216.48}{108}

or

 

acceleration of the safe=2.00 m/s^2

Hence, the acceleration of the metal safe will be  2.00 m/s²

A car traveling along the highway needs a certain amount of force exerted on it to stop it in a certain distance. More stopping
galben [10]

Answer:

Higher mass or higher speed

Explanation:

Higher mass will require more force

F= ma       if m goes up  F   goes up   to stop in the same distance
