Frequency:
Cardio : Five or more
HIIT: 5 or 4
Strength: 2-3 days on non-consecutive days a week
Intensity:
How hard you work during the session
For cardio : workout at your target heart rate.
For HIIT: varying intensity from high to low or rest ( no slow pace)
For strength: you should lift enough weight to complete the needed number of reps and sets.
Time:
For cardio 30- 60 min
For HIIT 45 min (short periods of bursts followed by rest)
For strength depends on the amount of weight.
Type:
Either cardio, HIIT or strength training (resistance training)

Explanation:
Answer. Due to stroking the piece of steel, the domains which are randomly arranged get aligned in the direction of stroking by the magnet. Due to this alignment of the domains, the piece of steel attains magnetic properties.
Answer:
Our estimate not done correctly because the width was unrealistic.
Explanation:
Given that,
Length = 6 m
Width = 0.5 m
We need to calculate the area of rectangular floor
Using formula of area

Where, l = length
w= width
Put the value into the formula


We need to find why this estimate not done correct
Using given data
We can say that,
We assume width was unrealistic.
The length of room is 6 m.
We know that,

So, the length would be 20 feet.
The width of room is 0.5 m.
The width of room would be 1.64 feet.
So, the area will be


Hence, Our estimate not done correctly because the width was unrealistic.
Answer:
its not moving at a constant velocity because it is slowing down
Explanation:
Answer:
The final kinetic energy is four times of initial kinetic energy when speed of the car doubles.
= 4 
Explanation:
Mass of the car = 770 kg
initial speed
= 23.1 
Final speed
= 46.2 
Initial kinetic energy
= 
⇒
= 0.5 × 770 × 
⇒
= 205440 J
Final kinetic energy
= 
⇒
= 0.5× 770 × 
⇒
= 821760 J
Thus
= 4 
Therefore the final kinetic energy is four times of initial kinetic energy when speed of the car doubles.
