Answer: d)temporal lobe

Explanation:

The temporal lobe is the part of the brain. It facilitates the interpretation of the sound and language. It is associated with helping in vision. If the damage is caused to the temporal lobe caused due to injury or infection will lead to problems related to memory, vision, and interpretation of language.

The scarlet fever includes the symptoms of blindness, problems associated with the speaking and hearing. The brain part which get damaged and affected in the scarlet fever is the temporal lobe.

Ans. (d). temporal lobe.

Temporal lobe is the region of the brain, which is associated with vision, and interpretation of language and sounds we hear. Damage to temporal lobe due to injury or infection can leads to problems with language skills, vision, and memory.

As in infant, scarlet fever ended up with blindness, problems with hearing and speaking, the brain area affected by the scarlet fever is 'temporal lobe.'

Thus, the correct answer is option (d).

To cook food, a microwave oven converts electrical energy intoenergy A) electromagnetic B) heat C) mechanical D) nuclear
Romashka-Z-Leto [24]

To cook food, a microwave oven converts electrical energy into electromagnetic energy. (A)  Specifically, it pours high-power RADIO waves into the box.

Water molecules and fat molecules resonate (jiggle) with the radio waves, and the heat is generated IN THE FOOD.

I work with microwave radios.  

-- To communicate high-speed data over a distance of 5 to 10 miles, we use a radio transmitter with a power output of 0.07 watt .

-- To communicate high-speed data over distances up to 80 miles, we use a radio transmitter with a power output of 1 to 2 watts.

-- To heat up a chunk of leftover meatloaf, a microwave oven pumps radio waves into the box with a power output of 1200 to 1500 watts ! !

nikklg [1K]

Answer:

Sodium formate is the sodium salt of formic acid which is given as HCOONa.

Explanation:

The basic structure of Sodium formate consists of following bonds:

  1. The main Ionic bond between the HCOO^- radical and Na^+.
  2. The  sigma covalent bonds between atom of H, atom of C and  both atoms of O.
  3. The pi bond between atom of C and one atom of O.

The structure along with lone pairs is given as attached

A swing that is 9.2m long has a child in it who is swinging. what is its period in seconds
Fantom [35]
The child on a swing can be modeled as a simple pendulum.  The period of a simple pendulum is given by

T=2 \pi \sqrt{ \frac{L}{g} }=2 \pi \sqrt{ \frac{9.2m}{9.8 \frac{m}{s^2} } }=6.09s

A ski lift has a one-way length of 1 km and a vertical rise of 200 m. The chairs are spaced 20 m apart, and each chair can seat
RSB [31]

Answer:

Explanation:

The question states that the chairs are spaced 20 m apart through a length of 1 km, or say, 1000 m.

It also does say that each chair weighs 250 kg, and as such the load is

M = 50 * 250

M = 12500.

Taking into consideration, the initial and final heights, we have

h1 = 0, h2 = 200 m

The work needed to raise the chairs,

W = mgh, where h = h2 - h1

W = 12500 * 9.81 * (200 - 0)

W = 2.54*10^7 J

The work is done at a rate of 10 km/h, and at a distance of 1 km, time taken would be

t = 1/10 = 0.1 h or say, 360 s

The power needed thus, is

P = W/t

P = 2.54*10^7 / 360

P = 68125 W, or 68 kW

Initial velocity, u = 0 m/s

Final velocity, v = 10 km/h = 2.78 m/s

Startup time, t is 17 s

Acceleration during the startup then is

a = (v - u)/t

a = 2.78/17

a = 0.163 m/s²

The power needed for the acceleration is

P = ½m [(v² - u²)/t]

P = ½ * 12500 * [2.78²/17]

P = 6250 * 0.455

P = 2844 W
