The stake, height and tether length of the tent form a right angle triangle where the tether length is the hypotenuse.
Applying Pythagoras theorem:
length² = height² + (stake distance)²
length = √(8² + 2²)
length = 8.5 feet
Answer:
the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s
Explanation:
It was made by god this is ture
Velocity of wave= wavelength/wave period;
i.e., 100/20=5 meter/sec
b) Equal to 243 N.
Explanation:
The total force acting on the car in the opposite direction including the road friction and air resistance is equal to 243 N.
This is in conformity with newton's third law of motion.
Newton's third law of motion states that "action and reaction are equal and opposite in direction. "
- The action force is that of the pull by Harry acting on the car.
- The reaction force is in the opposite direction.
- Both action and reaction force equal and opposite and magnitude and direction
