Answer:
2.29 m/s
Explanation:
given,
Speed of the stream to north,x = 3.3 m/s
speed of the ship,z = 8 m/s
Speed of the stream is in north direction, to move the ship in west direction ship should move in south direction.
To solve this a right angle triangle is constructed.
where speed of the stream is base and speed of cruise is hypotenuse.
now, speed of ship with respect to ground
z² = x² + y²
y² = z² - x²
y² = 8² - 3.3²

y = 2.29 m/s
Hence, the speed of the ship with respect to ground is equal to 2.29 m/s.
Answer:
83.3kg
Explanation:
GPE = m × g × h
GPE = mass of leopard × 10 × 36m

Dear Amrish
I have come to know that since your school has closed for the Autumn Break you have plenty of free time at your disposal at the moment. I would like to tell you that even I am having holidays now.
It has been a long time since we have spent some time together. If you are free, I would welcome to have your company this weekend. Why don’t you come over to my house and spend a day or so with me?
I am anxiously waiting for your reply.
Yours affectionately
your name
