try to be honest, even if it does hurt him its better than leading him, which might hurt him more
Answer: If your trying to break up with him , please do it in person and not over text . tell him why your leaving him and that maybe you both could be friends . don't say " i'm leaving because i can't do this anymore " ... the more you lie the more harder it'll be ... and yeah . if you wanna ask me questions you can ;)
Explanation:
A crowbar is used to lift a load of 1200 N by placing it at a distance of 25 cm from the fulcrum.
the force required at 60 cm from the fulcrum to balance the load.
Answer:
500 N
Explanation:
From the question,
Sum of clockwise moment = sum of anti clockwise moment.
F×d = F'×d'.................. Equation 1
Where F = Force applied to lift the load, d = distance, F' = Force required, d' = distance of the required force from the fulcrum
Make F' the subject of the equation
F' = F×d/d'.................. Equation 2
Given: F = 1200 N, d = 25 cm, d' = 60cm.
Substitute these values into equation 2
F' = 1200×25/60
F' = 500 N.
Hence the force required to balance the load is 500 N
A child pushes a toy truck 2.5 m across a floor with a constant force of 22 N. How much work does the child do on the toy truck?
22/2.5= 8.8 J
22 x 2.5= 55 W
22/2.5= 8.8 W
22 x 2.5= 55 J
Answer:
55j
Explanation:
work= force × distance
We have that When A child pushes a toy truck 2.5 m across a floor with a constant force of 22 N.The work done by the child on the toy truck
W= 55 Joules
22 x 2.5= 55 J
Option D
From the question we are told that
A child pushes a toy truck 2.5 m
A constant force of 22 N.
Generally the equation for the Workdone is mathematically given as
W=f*d
W=22N*2.5
W= 55 Joules
Therefore
When A child pushes a toy truck 2.5 m across a floor with a constant force of 22 N.The work done by the child on the toy truck
W= 55 Joules
22 x 2.5= 55 J
Option D

The work done by the toy car when it travels 2 m is 20 J.
The work done by the toy car when it travels 1 m is 10 J.
The work done by the toy car held 3.75 m above the ground is zero.
The work done by the toy car when it travels 7 m is 70 J.
The work done by the toy car when it travels 10 m is 100 J.
Work done by the toy car when it travels 2 mThe work done by the toy car when it travels 2 m is calculated as follows;
W = Fd
W = (ma)d
W = (2 x 5) x 2
W = 20 J
Work done by the toy car when it travels 1 mThe work done by the toy car when it travels 1 m is calculated as follows;
W = Fd
W = (ma)d
W = (2 x 5) x 1

The speed limit on an interstate highway is posted at 75mi/h. What is the speed in kilometers per hour? In feet per second?
Answer:
See explanation
Explanation:
The conversion factor from miles per hour to kilometers per hour is 1.609344.
Hence;
To convert 75mi/h to kilometers per hour,
75mi/h * 1.609344 = 120.7 kilometers per hour
b)
To convert 75mi/h to feet per second
Since
1 mile per hour = 1.46667 foot per second
75mi/h = 75 * 1.46667 = 110 feet per second

help me, what is the shape of solid?
Explanation:
Solids have a definite shape and definite volume.
Answer:
Solids have a definite shape and volume because the particles in them are held together tightly.
Explanation:
Liquids have a definite volume but their particles aren't held together as tightly as solids, so liquids take on the shape of the container they are in. Gases have no definite shape OR volume they just float around because the particles in them are so loose they can take on the shape and volume of any container.
32g of water at 60°C is poured into 60g of cold water at 15°C, which is contained in a
calorimeter of mass 40g, and S.H.C of water is 0.1Jg'K'. Neglecting heat loss show that
the resulting temperature is 29°C.
Explanation:
Let thermal capacity of the vessel be C' J K-1
Heat energy given by hot water = 40 x 4.2 x (60 - 30) = 5040 J
Heat energy taken by cold water = 50 x 4.2 x (30 - 20) = 2100 J
Heat energy taken by vessel = C' x (30 - 20) = 10 C' J
If there is no loss of heat energy,
Heat energy given by hot water = Heat energy taken by cold water and vessel
or 5040 = 2100 + 10 C'
or 10 C' = 2940
or C'= 294 J K-1
Thus, thermal capacity of vessel = 294 J K-1.

Direct current is the flow of current through a current carrying conductor in the same direction from positive to negative ends. Alternating current is the type of current our mains have where the current is constantly changing direction at a certain rate
Explanation:
Direct current (DC) is a form of electricity that has a unidirectional flow, such that the current path in the current carrying conductor of a circuit is, at all times, in a specific single direction
Alternating Current (AC) is electricity continuously reverses its direction of flow and the magnitude of electricity at a given frequency with time. It is the of current found in electric supply cables that are found in our houses

velocity- the speed of something in a given direction.
Explanation:
acceleration- increase in the rate or speed of something.
Solar energy heats the surface of the Earth, including the ground, rocks, and even roadways. As the temperature of these surfaces increases, heat energy is released back into the atmosphere, forming a pocket of warm air. As the warm air pocket rises, it is replaced by cooler air. This process is responsible for many of the weather patterns in our atmosphere and is known as

A worker drives a .500kg spike into a rail tie with a 2.50kg sledgehammer. The hammer hits the spike with a speed of 65.0 m/s. If one-third of the hammer's kenetic energy is converted to the internal energy of the hammer and spike, how much does the total internal energy increase?
Answer:
The increase internal energy is 1,760.41[tex]\overline 6[/tex] J
Explanation:
The given parameters of the worker, sledgehammer, and rail line are;
The mass of the spike driven into the rail, m₁ = 0.500 kg
The mass of the sledgehammer, m₂ = 2.50 kg
The speed of the sledgehammer, v = 65.0 m/s
The fraction of the hammers kinetic energy, KE, converted to the internal energy of the hammer and the spike, Δ[tex]E_{internal}[/tex] = 1/3 × KE
Therefore, we have;
The kinetic energy, KE, of the sledgehammer is given by KE = 1/2·m₂·v²
Where;
m₂ = The mass of the sledge hammer = 65.0 m/s
v = The velocity o the sledgehammer
∴ KE = 1/2 × 2.50 kg × (65.0 m/s)² = 5,281.25 J
Therefore;
The increase internal energy, Δ[tex]E_{internal}[/tex] = 1/3 × 5,281.25 J = 1760.41[tex]\overline 6[/tex] J

Find the amount of force if the body has pressure of 178 Pa on 18 mm²
Answer:
Force = 3.204Newton
Explanation:
Given the following data;
Pressure = 178
Area = 18 mm² to meter = 18/1000 = 0.018 m²
To find the force;
Force = pressure * area
Force = 178 * 0.018
Force = 3.204 Newton.
