The student can measure a liquid's volume by using a graduated cylinder, or a beaker. Mass can be measured by first weighing an empty container on a scale, and then by adding the liquid to the container and weighing it again.
Answer:
the buoyant force acting on the ice cube is 0.119 N
Explanation:
given,
volume of ice cube = 15 cm³ = 15 × 10⁻⁶ m³
density of ice cube = 917 kg/m³
density of ethyl alcohol = 811 kg/m³
buoyant force = ?
The density of ice is more than ethyl alcohol hence it will sink.
buoyant force acting on the ice cube = ρ V g
= 811 × 15 × 10⁻⁶ × 9.81
=0.119 N
so, the buoyant force acting on the ice cube is 0.119 N
If Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.
<h3>What is average speed? </h3>
The average speed of an object is the ratio of total distance to total time of motion.
V = total distance/total time
For Frank to be in Tampa by noon, he must spend atleast 4 hours 30 minutes on the road.
18.3 mph = d/4.5 h
d = 82.35 miles
The distance between Gainesville and Tampa is 82.35 miles.
Thus, we can conclude that, if Frank leaves Gainesville at 7:30 am, the time he should arrive in Tampa is 12.00 pm after spending 4 hours 30 minutes on the road.

Answer:
15 N
Explanation:
The magnetic force on a piece of current-carrying wire is given by:
where
I is the current in the wire
L is the length of the piece of wire
B is the magnetic field strength
is the angle between the direction of B and I
In this problem:
I = 10 A
B = 0.3 T
L = 5 m
Substituting into the equation, we find
Crossed electric field lines indicate A) a field pointing in two directions
