Anna drives north at a speed of 50 km/h for the first hour. Then, she drives north for a second hour but slows down to 30 km/h.

Compare or contrast the first hour of her trip to the second hour of her trip.
Group of answer choices

The distance is greater in the first hour because her speed is faster.

The distance is greater in the second hour because her speed is slower.

The displacement is the same for both hours because she is travelling north the entire time.

The distances are the same for both hours because she is travelling north the entire time.

Answer:

The correct answer is A The distance is greater in the first hour because her speed is faster.

Explanation:

During the first hour, Anna is driving at a speed of 50 km/h. During the second hour, she is only driving at a speed of 30 km/h. The faster she goes, the farther she will go.

Hope this helps,

Answer:

The distance is greater in the first hour because her speed is faster.

Explanation:

As we know that the distance of an object is given as

d = speed \times time

here we know that in first hour speed is

v_1 = 50 km/h Towards North

So the distance moved by the car is

d_1 = 50 \times 1

d_1 = 50 km

Now similarly we have speed in next hour as

v_2 = 30 km/h Towards North

so distance will be

d_2 = v_2 t

d_2 = 30 \times 1

d_2 = 30 km

So correct answer will be

The distance is greater in the first hour because her speed is faster.

DENIUS [597]

Answer:

B) shrinks

Explanation:

The magnetic force is a force exerted between two magnets, or two magnetic materials, or also on an electric charge moving in a magnetic field.

If we talk about magnetic material, the magnetic field they generates can be represented using a dipole: essentially, they have a north pole (where the lines of the field go out) and a south pole (where the lines of the field go in).

Also, the lines spread apart as we move away from the magnet itself. This means that the strength of the field (and so, the intensity of the force) decreases as we move away from the magnet.

Using this description, we can now understand that when we move the paper clip further from the magnet, the force exerted on the clip decreases, as the magnetic field becomes weaker. So, the correct answer is B.

What is the wavelength of microwave of 3 x 10 9 Hz frequency?
jok3333 [9.3K]

The wavelength of a microwave of 3 x 10^9 Hz frequency is 0.1 m.

The wavelength of a microwave of 3 x 10^9 Hz frequency is calculated using the equation λ = c/f, where λ is the wavelength, c is the speed of light, and f is the frequency.

The speed of light is approximately 3 x 10^8 m/s. Therefore, the wavelength of a microwave of 3 x 10^9 Hz frequency can be calculated as follows:

λ = 3 x 10^8 m/s/3 x 10^9 Hz

= 0.1 m.

Therefore,the wavelength of a microwave of 3 x 10^9 Hz frequency is 0.1 m.

Microwaves are electromagnetic waves that have a frequency between 300 MHz to 300 GHz and a wavelength from 1 mm to 1 m. Microwaves have a variety of uses, including communications, radar, and cooking. Microwave radiation is absorbed by water, fats, and sugars, which is why it is used for cooking.

The frequency of a microwave is usually expressed in megahertz (MHz) or gigahertz (GHz). One megahertz is equal to one million hertz and one gigahertz is equal to one billion hertz. The frequency of a microwave determines its wavelength; the higher the frequency, the shorter the wavelength.
