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:
True
Explanation:
For any equation to be balanced, be it elemental equation or radioactive decay equation, the number of atoms on the left must balance the number of atoms of the right. The same is true for alpha decay as the number of protons on the left side must equal the number of protons on the right side?
Answer:
True
Explanation:
kinetic energy is proportional to temperature
Answer: 1. higher than it was before they started running
Explanation: As the vacationers run towards the back(stern) of the ship the exerting more pressure against the pressure exerted by the wave supporting the moving ship,the pressure exerted on the moving ship will be increased, leading to a slight increase in the speed of the ship compared to the speed before they started running towards the back(stern) of the ship.
