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.

An object weighs 2600 N on Jupiter (g = 26). What is its weight on the Earth (g = 10)?
HELP ASAP!
Answer:
Weight = 1000N
Hope this helps... Have a good day!!
Answer: 1000N
Explanation:
Weight of object = 2600N
Jupiter g = 26
Now converting to mass
2600/26
= 100 kg
Earth g = 10
Converting to Newtons
100×10

Question 10 of 10
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.

Which element has atoms with valence electrons in a higher energy level than those of calcium (Ca)?
(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.

define average velocity
Answer:
The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another.
Explanation:
Average velocity is a vector quantity. The SI unit is meters per second. However, any distance unit per any time unit can be used when necessary, such as miles per hour (mph) or kilometer per hour (kmph)
Answer:
the ratio of total displacement by total time taken
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.

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.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.
