_______ currents assist in the transfer of thermal energy from warmer climates to cooler climates.
Leya [2.2K]
<span>It is convection currents that carry thermal energy from warmer places to cooler places. The process operates upon planetary scales, as suggested by the question, but also operates on more local scales such as in your own house. For example, if there is a heater within a single room within your house, convection will drive heat energy to adjacent colder rooms. </span>

If an object has an increasing positive acceleration, what can we assume about the forces on it?
Nesterboy [21]

Answer:

F = M a    is a vector equation

F has the same sign as A and is in the same direction as the vector a

If a is positive then F must also be positive

A student throws a set of keys vertically upward to her sorority sister, who is in a window 3.50 m above. The second student cat
Mkey [24]

Answer:

a) 8.58 m/s upward

b) -2.211 m/s downward

Explanation:

Let gravitational acceleration g = -9.81m/s2. This is negative because it deceleration the upward motion of the key.

(a)We have the following equation of motion

s = v_0t + gt^2/2

where v_0 is the initial upward velocity of the keys, t = 1.1s is the time it takes for the keys to travel a distance of s = 3.5 m

3.5 = v_01.1 - 9.81*1.1^2/2

3.5 = 1.1v_0 - 5.94

1.1v_0 = 3.5 + 5.94 = 9.44

v_0 = 9.44 / 1.1 = 8.58 m/s

So the keys were thrown initially upward with a speed of 8.58 m/s

(b) If the initial velocity of the key is 8.58 m/s and it is subjected to a deceleration of 9.81m/s2 for 1.1s then the velocity right at the 1.1s instant is

v = v_0 + gt = 8.58 - 9.81*1.1 = -2.211 m/s

So they keys would have a downward speed of 2.211 m/s

The period of a wave is 20 ms (milliseconds) and its wavelength is 4 cm. Calculate:
IgorLugansk [536]

Answer:

A. 50 Hz

B. 2 m/s

Explanation:

We'll begin by converting 20 ms to s. This can be obtained as follow:

1000 ms = 1 s

Therefore,

20 ms = 20 ms × 1 s / 1000 ms

20 ms = 0.02 s

Next, we shall convert the value of the wavelength (i.e 4cm) to m. This can be obtained as follow:

100 cm = 1 m

Therefore,

4 cm = 4 cm × 1 m / 100 cm

4 cm = 0.04 m

A. Determination of the frequency.

Period (T) = 0.02 s

Frequency (f) =?

f = 1 / T

f = 1 / 0.02

f = 50 Hz

Therefore, the frequency of the wave is 50 Hz

B. Determination of the velocity.

Wavelength (λ) = 0.04 m

Frequency (f) = 50 Hz

Velocity (v) =?

v = λf

V = 0.04 × 50

v = 2 m/s

Therefore, the velocity of the wave is 2 m/s
