Answer:

Mass is the amount of matter in an object. Mass is often measured in kilograms or grams. The masses of two objects are compared using a balance. Weight is the downward pull on an object due to gravity. Weight is often measured in newtons or pounds, using a spring scale.

Weight depends on gravity. Weight is mass times gravity (mg). So if you were on another planet, your weight might change depending on the gravity there.
On the other hand, mass is not affected by gravity, so it will be the same on whichever planet you go.

consider a charge of -15.0 mCmoving to the right a 2.00x10^6 m/s in a mganetic field of .0300 T pointing upwards. What is the ma

Answer:

a = 1.13×10^-8 m/s²

Explanation:

$f = ma = qvb \\ a = \frac{qvb}{m}$

q = 15×10^-3 C

v = 2×10^6 m/s

B = 0.03 T

m = 8.00 x10^10 kg

a = 900/8 x10^10

a = 1.13×10^-8 m/s²

What is simple machines and it type.I need it today please

Simple machines are tools, devices or objects that are used to make work easier.

TYPES OF SIMPLE MACHINES.

Levers
Inclined Plane
Wedges
Screw
Pulley
Wheel & Axle

THE LEVERS

A lever is simply a plank or ridge beam that is free to rotate on a pivot.

PARTS OF A LEVER

Load
Effort
Fulcrum or pivot

CLASSES OF LEVERS

THE FIRST CLASS LEVER

In this class, the FULCRUM is between the EFFORT and the LOAD. The mechanical advantage is more if the load is closer to the FULCRUM. Examples: seesaws, boat oars and crowbars.

THE SECOND CLASS LEVER

In this class, the LOAD is between the EFFORT and the FULCRUM. The mechanical advantage is more if the LOAD is closer to the FULCRUM. Example: wheelbarrow.

THE THIRD CLASS LEVER

In this class, the EFFORT is between the LOAD and the FULCRUM. The mechanical advantage is more if the EFFORT is closer to the LOAD. Example: garden shovel.

THE INCLINED PLANE OR RAMP

An inclined plane is a simple machine with a sloping surface. It makes it easier for us to move objects from lower grounds to higher grounds.

WEDGES

A wedge is simply a triangular tool, often made of wood, stone, metal or plastic. It is thick at one end and tapers to a thin or sharp edge at the other end. Examples: knife, axe, doorstopper, nail, blade on the snow plough or farmer grader.

PULLEY

A pulley is simply a wheel with a groove in it, and a rope in the groove. It is used to lift heavy objects from the ground to high places.

WHEEL & AXLE

Involves two circular objects joined at the center. It works when force is applied to the wheel or when force is applied to the axle. Example: door knob.

F=ma
Mass times acceleration
We have g (10ms^_2) and a (1 given)
So total would be

In an area in which electricity costs 8 cents/kilowatt-hour, a 5 kW clothes dryer runs for 90 minutes to dry a load of laundry.

Over [174]

$0.60
90 mins is 1.5 hrs
5 kW × 1.5 = 7.5 kWh
7.5 kWh × $0.08 = $0.60
