Answer:

To increase the current, decrease the resistance.  

Explanation:

Ohm's law relates the current, resistance and the voltage. This law states that "the potential difference or the voltage across the ends of any conductor is related directly to the current flowing through it". The mathematical relationship is given by :

V = I × R

Where

R = resistance of the circuit

I=\dfrac{V}{R}

The current is inversely proportional to the resistance of the circuit. Hence, the correct statement about the Ohm's law is (a) " To increase the current, decrease the resistance".

One of the things that Ohm's law suggests is that the current in
a circuit is inversely proportional to the resistance in the circuit. 

That's what choice-A says ... if the resistance decreases, then
the current will increase.

A 3.0-kilogram toy dump truck moving with a speed of 4.0 m/s starts up a ramp. How high does the truck roll before it stops?
baherus [9]

Before it reaches the ramp, the toy's kinetic energy is

                                        (1/2) (mass) (speed²)

                                   =   (1/2) (3 kg) (16 m²/s²)

                                   =          24 Joules .

On the way up the ramp, its kinetic energy will change to
gravitational potential energy, and it'll stop when it's height
gives it  24 joules of potential energy.

         Potential energy  =  (mass) (gravity) (height)

                    24  joules  =  (3 kg) (9.8 m/s²) (height)

Divide each side by  29.4 kg-m/s²  (that's the same as 29.4 newtons):

                    Height  =  24 joules / 29.4 newtons

                                =      0.816 meter higher than the bottom of the ramp.

Why do you think that some asteroids tumble end over end through space while other asteroids rotate around their axis?
Scilla [17]
Asteroids do this because of Newton's Third Law. When a asteroid hits something, it will keep on moving (spinning) until it hits something else.

11) Arthur and Betty start walking toward each other when they are 100 m apart. Arthur has a speed of 3.0 m/s and Betty has a sp
sleet_krkn [62]

Answer:

100 m

Explanation:

Arthur and Betty should be walking the same amount of time if they start walking at the same time and stop when they meet = t

Speed of Arthur = 3 m/s

Speed of Betty = 2 m/s

Distance = Speed × time

Distance covered by Arthur = 3t

Distance covered by Betty = 2t

The distance covered by both of them will be 100 m

3t+2t=100\\\Rightarrow 5t=100\\\Rightarrow t=\frac{100}{5}\\\Rightarrow t=20\ s

The speed of dog is 5 m/s

Spot is running back and forth at 5 m/s for 20 seconds

In 20 seconds the distance covered by the dog is

\mathbf{5\times 20}=\mathbf{100\ m}

A hypothetical planet has a mass of 1.66 times that of Earth, but the same radius. What is gravitiy near its surface?
baherus [9]

Answer: 16.22 m/s^2

Explanation: g= GM/r^2 G= (6.67x 10^-11) M= 1.66(6x 10^24) r=(6400x 10^3) so

((6.67x10^-11)(1.66x 6x 10^24))/ (6400x10^3)^2 = 16.22 m/s^2
