You skip north for 12 minutes to your best friend's house that is 1.5 kilometers away. What is your average velocity?

The net force on the car for either case will be zero, since the car is moving at a constant velocity.

The net force on the car is the sum of all the forces acting on the car.

∑F = ma

When the car is on a level road, the only two forces acting on the car is the applied force and frictional force of the road.

F - Ff = 0

The net force will be zero, since the car is moving at a constant velocity.

The forces acting on the car at the uphill is the applied force, weight of the car acting downwards and the frictional force acting opposite direction.

F - Wsinθ - μFₙcosθ = 0

The net force will be zero, since the car is moving at a constant velocity.

Answer:

It's B (electrical force and magnetic force) I just took the test.

The two forces can Danielle's device produce will be an electrical force and magnetic force. Daniel forms a coil resulting in both forces.

Electric Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force. it is the ratio of voltage to the distance between them.

Danielle took an iron nail and wrapped thin copper wire around it, then connected the ends of the copper wire to a battery.

A coil of wire that carries an electric current is a solenoid. A solenoid is an electromagnet formed by a helical coil of wire. Which generates a magnetic field when an electric current is passed through the coil.

A solenoid is a form of coil that produces a magnetic field when the electric current is passed through it. A solenoid is created when a conductive wire is used to make a loop.

The two forces can Danielle's device produce will be an electrical force and magnetic force. Daniel forms a coil resulting in both forces.

Hence option B is correct.

Answer:

Gravity stronger closer to the core of the earth

Explanation:

The gravity applied to the feet is stronger than to the upper part of the body for example the brain because of the distance it is between the body part and the core of the earth where the gravity force is pulling towards. Even though the difference between the gravity force between the brain and the feet is minimal it is still a greater force at the feet than at the brain

Answer:

pls first attach the fig.

The graph in the figure shows the position of a particle as it travels along the x-axis. The magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s is 1.3 m / s. Therefore, option B is correct.

The term average speed is defined as the total distance traveled by the object in a particular time interval.

In the kinematics studies the movement of bodies, give the relationships between position, velocity and acceleration. In the special case that the acceleration is zero the motion is known as uniform motion.

       v = Δ x / Δt

Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.

Therefore,

v =  2.0 - ( - 2.0 ) / 4.0 - 1.0

v = 1.33 m / s          

Thus, The magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s is 1.3 m / s, option B is correct.

The normal force of the ferris wheel on a 10kg toddler at the very bottom of the ferris wheel is 102.41 N.

The normal force of the ferris wheel on a 10kg toddler at the very bottom of the ferris wheel is calculated as follows;

Fn = Fc + mg

Fn = mω²r + mg

Fn = m(ω²r + g)

where;

Fn = 10(0.21² x 10  + 9.8)

Fn = 102.41 N

Wavelength = 6m

Explanation:

Given that,

→ Transverse wave = 15 m/s

→ Frequency = 2.5 Hz

Then the required wavelength is,

→ Transverse wave ÷ Frequency

→ 15 ÷ 2.5

→ 15/2.5 = 6m

Hence, the wavelength is 6m.
