alina1380 [7]

Answer:

The dog should be given half of 100 mg tablet in the morning and another half of 100 mg tablet in an evening.

Weight of the dog = 50 pounds = 22.68 kg

1 kg = 2.205 pounds

Amount of daily dose prescribed by doctor = 4.4 mg/kg

Total mount of dose = 4.4 mg/kg × 22.68 kg = 99.79 mg

99.79 mg ≈ 100 mg

49.89 mg ≈ 50 mg

So, according to doctor prescription dog should be given half 100 mg tablet in the morning and another half of 100 mg tablet in an evening.

<h2>A wind turbine generating electricity involves electromagnetic energy. thermal energy. solar energy. mechanical energy. chemical energy. nuclear energy.</h2><h2>ans: electromagnetic energy, thermal energy, solar energy, and mechanical energy.</h2>

Explanation:

Wind mill

It consist of shaft pole and blades that can rotate .

It converts wind energy into electrical energy .

The shaft of wind mill is connected to shaft of armature of generator .

When the fast moving wind rotates the blades of windmill its shaft rotates, armature rotates hence electricity is produced which is further used for various purposes .  

Advantage of using wing energy

it is natural renewable resource  

It is eco friendly  

Disadvantage :

1. It cant be established everywhere  

2. It requires large area  

3. It is an expensive project  

4. Wind dosen't blow all the time so win energy cant be produced every time  

5. Minimum speed of wind required is 15km per hour .

So, the wind turbine generating electricity involves mechanical energy of wing and blades .
