A television weighs 8.50 pounds. How many grams is this? (Hint: You need to
use two unit conversion fractions. 1 pound equals about 0.454 kg.)
A. 3860 g
B. 18.7 g
C. 18,700 g
D. 3.86 g
SUBWT
C. 18,700g
Explanation:
8.50+1
then -0.454
The television weighs 8.50 pounds which is equal to 3860 grams. Hence, option (A) is correct.
What is mass?In physics, mass is a numerical representation of inertia, a fundamental characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force.
The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).
Given that: A television weighs 8.50 pounds.
And 1 pound equals about 0.454 kg.
Hence, the television weighs = 8.50 pounds × (0.454 kg/1 pound).
= 3.859 kg.
Hence, the television weighs = 3.859 kg × (1000 g/1kg).
= 3859 grams
= 3860 grams ( approx.)
Hence, the television weighs 3860 grams.

an object is sliding down in clean plane the velocity change at a constant rate from 10 cm to 15 CM in 2 second what is it acceleration ?
Initial velocity=10m/s=u
Final velocity=v=15m/s
Time=t=2s
[tex]\boxed{\sf Acceleration=\dfrac{v-u}{t}}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{15-10}{2}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{5}{2}[/tex]
[tex]\\ \sf\longmapsto Acceleration=2.5m/s^2[/tex]
Answer: a = 2.5 cm/s²
Explanation:
Acceleration = (Final velocity - Initial Velocity)/time taken
a = v-u/t
Initial velocity = 10 cm/s
Final velocity = 15 cm/s
Time = 2 seconds
a = (15-10)/2
a = 5/2
a = 2.5 cm/s²
Therefore the acceleration is 2.5 cm/s²

What are the correct units for force and for weight?
Answer:
The associated SI unit of force and weight is the Newton, with 1 kilogram weighing 9.8 Newtons under standard conditions on the Earth's surface. However, in the US common units, the pound is the unit of force (and therefore weight). The pound is the widely used unit for commerce.

6. A car moving in a straight line at constant speed:
A. is accelerating.
B. is decelerating.
C. must be on a downhill slope.
D. has no overall force acting on it.
Answer:
D. has no overall force acting on it.
Explanation:
Why?
Because in a straight line at the constant speed means the car moving in the same velocity, which is not acceleration neither deceleration, and it cannot be on a downhill slope. So the correct answer is
→ D. has no overall force acting on it.How does electric force affect an atom?

In a collision, the human body will strike the seatbelt, steering wheel, dash or windshield at? Group of answer choices only 10 to 15 miles per hour the same speed as the vehicle twice the speed of the vehicle one half the speed of the vehicle
Answer:
isn't this kinda like math
Explanation:
In a collision, the human body will strike the seatbelt, steering wheel, dash, or windshield at the same speed as the vehicle.
A collision is when one object comes in contact with another, leading to an abrupt and forceful impact. This means that a collision happens when one object hits another surface or object with an extreme impact that causes injuries or damages.
There are three theories of collision, among which the "human collision" is the second theory. In this theory, the impact of a collision between the human body and the external surface happens after the collision occurs. But the force of the impact remains the same, meaning the force with which the body hits the other surface is at the same speed as the vehicle prior to the collision. This is because while the collision may have occurred, the body is still moving at the same speed as the vehicle, thereby resulting in the same speed of the vehicle as that of the force of impact. So, the human body will strike the external or opposite surface at the speed of the vehicle.Prior to a collision, the body inside the vehicle is moving at the speed of the vehicle. So, when a collision occurs, the body continues to move with that speed even though the vehicle may have halted. Thus, the human body will strike at the same speed as the vehicle.

what is the shape of the line graph that shows the temperature change over time of the liquid before it starts to boil?
The line graph showing the temperature change over time of a liquid before it boils has an upward-sloping trend as heat is applied until it reaches its boiling point, with fluctuations due to heat transfer rate changes.
What is the heat transfer rate?Heat transfer rate refers to the amount of heat energy transferred per unit of time between two objects or substances that are at different temperatures. It is a measure of how quickly heat is transferred between two objects or substances and is influenced by factors such as the temperature difference between the objects, the thermal conductivity of the materials, the surface area in contact, and the type of heat transfer mechanism involved (conduction, convection, or radiation). Heat transfer rate is often expressed in units of watts or BTUs per unit of time (e.g., watts/second or BTUs/hour).
Here in the Question,
The shape of the line graph that shows the temperature change over time of the liquid before it starts to boil is generally an upward-sloping line. As heat is applied to the liquid, its temperature will increase gradually until it reaches its boiling point. The rate of temperature increase may not be constant, and there may be some fluctuations due to factors such as changes in the rate of heat transfer.
Therefore, the trend of the line graph will be upward-sloping until the liquid reaches its boiling point.

A school bus in the oncoming lane of a 4-lane road is flashing. You should: * 1 point
-
O A. Stop until the flashing red lights turn off.
O B. Stop only if children are unloading:
O C. Wait until the flashing lights are yellow.
O D. Use caution as you pass the bus.
Answer:
A
Explanation:
and that is a very strange question in physics ...
it actually depends on what state you are in.
California for example requires all to stop unconditionally, I think. while in many other states it is the rule, if the 4-lane road is separating both driving direction by a barrier or raised intermediate area, you don't have to stop when going in the opposite direction.
so, it is either A or D depending on your state.
B and C never apply.

(1 point)
oxygen (O)
lithium (Li)
bromine (Br)
cesium (Cs)
Lithium element contains one electron therefore valence electron will be one.
The highest level of energy is due to valence electrons which are available to the atom.
The calcium has 2 valence electrons which has electrons with high energy.
These energy will be used by the electron during the chemical reaction, and they will either lose or gain valence electron.

2. a. in which principle does simple machine works?
Answer:
A simple machine uses a single applied force to do work against a single load force
Ignoring the friction losses. The work done on the load is equal to the work done with the applied energy. The machine can increase the amount of output power, with a corresponding drop in the distance transported by the load.
