Answer: Density--> the amount of mass in a given volume
Boiling point: the tempeture when a liquid becomes gas
Conductivity: the ability of a subtance to transfer heat or electricety
Bouyant force: The upward force of an object in a liquid
soulibility: the ability of a subtance to disolve in other.
sorry for bad spelling
Explanation:
Answer: 90 km/hr
Explanation:
Speed= distance divided by time
540/6
= 90km/hr
Answer:
Poke or kick the boxes. The sand box is the one that resists the most
Explanation:
The one that resists the most a change in motion (inertia) is the one with the greater mass—the one filled with sand. Since we cannot open the boxes or perform any weight measurement we can distinguish them by their inertia. Sand has greater mass and thus greater inertia
Answer: Hydroplaning
Explanation: Hydroplaning is the skiding of a high speed vehicle when water builds beneath the wheels when driving through standing water.
It is usually caused by factors such as High speed,Standing water,deflated tyres. It is strongly recommended that when driving in standing water a driver should drive at a slow and steady speed and always to ensure that the vehicle tyres are adequately inflated with air,this is one of the causes of vehicular accidents during rainy season or flood.
Answer:
F = 160.0 N
Explanation:
Given: Soccer payer with a mass = 80 kg, force = 20 N
To find: force
Formula: 
Solution: It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
F = m × a
F = 20 kg - 10 = 2
F = 80 × 2 = 160
F = 160.0 N
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
