Can you put the answers, if there are any?
Once you do, Ill respond with a answer asap!
:)
Answer: F = 0.17N
Explanation: From the Newton second law of motion.
F= m(v-u)/t.
V=180km/hr = 180×1000/3600= 50m/s
U= 160km/hr = 160×1000/3600= 44.44m/s
t= 5secs
F=m(v-u)/t
F= 0.150(50-44.44)/5
F=0.150×5.56/5
F= 0.835/5
F= 0.17N rounded to two decimal places.
Answer: When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel. Furthermore, when a liquid is poured from one vessel to another, it retains its volume (as long as there is no vaporization or change in temperature) but not its shape.
Explanation: A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.
The formula that links voltage (V), resistance (R) and current intensity (I) is
Solve this formula for I to get
Plug your values for V and R and you'll get the current.
