Answer:

Mass measures the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg). Volume measures the amount of space that a substance or an object takes up. The basic SI unit for volume is the cubic meter (m3)

Answer:

Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

Explanation:

Interesting fact...

Why are there differences between the cooling rates of sand and water? Sand cools off faster than water because sand is a solid. Water heats up slower and cools off slower than sand. Sand heats up faster and cools off faster than water.

As a variable and to count as land. As if you were at a beach, this sand would count as the sand that the sun would be beaming on. ^^

Explanation:

The cars will slow down as a result of unbalanced forces and negative acceleration.

Inertia is the ability of an object to continue its current motion until and unless some external force causes its speed or direction to change. Inertia is described in the Newton's first law of Motion.

The cars are slowed due to negative acceleration of the object eventually to a stop, because of these unbalanced forces due to friction which are acting on them. The riders, which have inertia, are also acted on by the unbalanced forces throughout the ride causing them to change their state of motion.

A student lists some possible ways to investigate the transfer of kinetic energy using ice in a sample of water. The procedure would be best to investigate the transfer of kinetic energy is Determine temperature and mass of water. Put ice in water. Record the time for ice to melt. Therefore, option 4 is correct.

The term kinetic energy is define as the energy of motion, observable as the movement of an object. The formula of kinetic energy is as follows:

Kinetic energy = 1/2 mv²

Kinetic energy exists in every moving object and particle. Kinetic energy is demonstrated by a person walking, a soaring baseball, a crumb falling from a table, and a charged particle in an electric field.

Kinetic energy is the energy held by a moving object. Kinetic energy exists in the earth's rotation around the sun, you walking down the street, and molecules moving in space.

Answer:

Explanation:

The Force of Friction = N * coefficient of static friction

N = m * g

=> The Force of Friction = m * g * coefficient of static friction

The Force of Friction = 100 * 10 * 0.4 = 400 (N)

The Force of Friction > The Force of John

=> It won't move!

The bench will not move because the friction force is more than john's applied force. Friction force= 392 N

Calculation

[tex]f_{k} =[/tex][tex]u_{k} *F_{N}[/tex]

where,

[tex]f_{k}[/tex] is friction force,

[tex]u_{k}[/tex] is coefficient of friction.

[tex]F_{N}[/tex] is the normal force

⇒[tex]f_{k} =0.4(100*9.8)=392 N[/tex].

Hence Force applied by john, 380N is less than the Frictional force, 392N.

Answer:

The first one (Work = 160,000 Nm, Power = 160, 000 Nm/sec)

Explanation:

hope this helps :)

A force of 1000 pounds drags a truck 50 feet in 10 seconds. then the work accomplished is 50000 lbs feet and the power required was 5000ft-lbs/sec.

Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. Balanced forces are those forces which are opposite in direction and equal in magnitude. When Net force acting on a body is zero then we call it as balanced force. Balanced force is not responsible for the motion of the body. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force. Unbalanced forces are those when resultant of all the forces is not equal to zero is called as unbalanced force. unbalanced force is responsible for the motion of the body.

Given,

F = 1000 pound

s = 50 feet

t = 10 s

Work = F.s = 1000 * 50 = 50000 lbs feet

Power = Work/time = 50000/10 = 5000ft-lbs/sec

Hence option A is correct.

Explanation:

The acceleration of the horse's speed which is running at a speed of 35 m/s when it's rider pulls up on the reigns will be -4 m/s².

Acceleration can be defined as the rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both the magnitude and direction. The SI unit of acceleration is m/s² or ms⁻².

The expression for acceleration will be:

a = (v-u)/ t

v = 15m/s,

u = 35m/s,

t = 5 sec,

a = (15-35)/ 5

a = -20/ 5

a = -4 m/s²

Therefore, there will a negative acceleration of 4 meters per second square.

Answer: The water Molecules of sample 1 are moving faster

Explanation:

The temperature of the sample in which the color spreads quickly is higher than sample 1. Hence, statement d is correct.

Kinetic energy of a substance is the energy generated by virtue of its motion. It is dependent on the mass and velocity of the substance. Temperature of the system also affects the kinetic energy of substance.

According to kinetic theory of matter, as thermal energy increases, kinetic energy of the particles also increases leading to more effective collisions results in reactions.

Here, the color spreads more easily in sample 2 because the higher temperature of the solution provide enough thermal energy for the liquid particles to gain kinetic energy to easily move through the solution. Thus, statement d is correct.

Answer:Both types involve multiple atoms coming together to form a more complex structure.Both types of bonding result in atoms becoming more stable in the group than they were individually. Both types of bonding are exothermic as the potential energy of the participants is lowered as they form the bond. Ionic bonding occurs between atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons. Covalent bonding occurs between atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.

By transferring electrons, ionic bonding leads to the formation of charged particles that have either an excess of protons (cation) due to the loss of electrons or an excess of electrons (anion) due to the gain of electrons. Covalent compounds contain neutral atoms.The electrostatic attraction that occurs in ionic bonding is between cations and anions. The electrostatic attraction in covalent bonding arises from a shared electron’s attraction for its original nucleus as well as the nucleus of the sharing atom.

Ions bond in a pattern that maximizes attractions between oppositely charged ions and minimizes repulsions between like charged ions. The geometric pattern that arises is called the crystal lattice and is consistent throughout the crystal. All ions are held by a network of ionic bonds which are considered strong intramolecular forces. Atoms in a covalent compound are held together by covalent bonds which are also considered strong intramolecular forces. In the solid, crystalline state, both types lead to regular, ordered patterns and structures.

Both types of compounds can undergo changes in physical state under the right conditions of temperature and pressure.

Both types of compounds have a net neutral charge.

Both types of compounds contain a fixed ratio of participants that is represented by the subscripts in their chemical formulas (they do not require a 1:1 ratio).

Answer: For forces on flat rigid bodies such as a wall, it is less direct in the calculation of work done as force times distance or displacement compared to other situations. You will have to calculate the pressure exerted first which will be P = F/A, where F is the force as above in Newtons, and A is the area of the wall first. There should also be a pressure limit for the wall in question based on what it is composed of and its dimensions from structural mechanics. The exerted force must exceed the upper limit of tolerated force to break the wall. In any case even without breaking the wall, using very accurate optical technology you can estimate the displacement now a days however minute, or the change in the form of volume of displacement also due to the pressure. Here Work done can be given still as follows : W = F •d, or W = P •V, or W = (F/A)•V. Here V will be the approximate
