Answer:

a.work done=force *displacement

=500N*46m

=23000 Joule

b.power=work done/time taken

=23000/25

=920 watt

c.GPE=m*g*h(m=mass,g=gravity due to acceleration,h=height)

=60kg*9.8m/s*14m

=8232 joule

a 2.00 kg friction-less block is attached to an ideal spring with force constant 315 N/m.Initially, the spring is neither stretc

Setler [38]

Answer

given,

mass of block, m = 2 Kg

spring constant, k = 315 N/m

speed of the block, v = 12 m/s

a) Amplitude of the motion

$A = v \sqrt{\dfrac{k}{m}}$

$A =\dfrac{12}{\sqrt{\dfrac{315}{2}}}$

A = 0.956 m

b) maximum acceleration of the block

$a_{max}= A \dfrac{k}{m}$

$a_{max}= 0.956\times \dfrac{315}{2}$

$a_{max}= 150.57\ m/s^2$

c) maximum Force

$F_{max} = m a_{max}$

$F_{max} = 2\times 150.57$

$F_{max} = 301.14\ N$

All matter is made up of subatomic particles that contain atoms.TrueFalse

antiseptic1488 [7]

All matter is made up of subatomic particles that contain atoms. This is false statement.

Everything in the universe is made of matter, and so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: <u>protons, neutrons, and electrons</u>.

All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.

Matter is anything which have mass and occupy some volume.

On earth, solid, liquid, and gas are the most common states of matter. Not only is water the most common substance on earth, but it is also the only substance that commonly appears as a solid, a liquid, and a gas within the normal range of earth's temperatures.

The magnetic field of a light wave oscillates parallel to a y axis and is given by by = bmsin(kz – ?t. (a in what direction does

-Dominant- [34]

In this case the coordinate z is multiplied by your wave vector k, so it travels along z. Note that the electric field will be oscillating along the x direction. H and E are perpendicular to the direction of travel in vacuum.

Eight books, each 4.6 cm thick and of mass 1.8 kg, lie on a flat table. How much work work is required to stack them on top of o

pantera1 [17]

Answer:

529.92Newton Meters

Explanation:

Work=force x displacement

8books in total

force is 1.8kg

dispplacement is 4.6cm

times both units by 8 and u get

force - 14,4

displacement - 36.8

now times boht together and u get 529.92nm

Define the term antinode and explain how standing waves form.

Otrada [13]

Answer:

standing wave, also called stationary wave, combination of two waves moving in opposite directions, each having the same amplitude and frequency.

For oppositely moving waves, interference produces an oscillating wave fixed in space. fixed nodes in a standing wave. Location of fixed nodes in a standing wave

these are the points that undergo the maximum displacement during each vibrational cycle of the standing wave. In a sense, these points are the opposite of nodes, and so they are called antinodes. A standing wave pattern always consists of an alternating pattern of nodes and antinodes
