A car is travel with velocity of 150 km/hr east. It traveled a distance of 500 km. How long did it travel for.
Answers
Explanation:
V= s / t
150 km/hr = 500 km / t
t = 500 km ÷ 150 km/hr
t = 10/3 hr (3 hrs 19 mins 49 sec)?
I'm not sure tho^^
Answer:
[tex]\boxed {\tt \frac{10}{3} \ hours}[/tex]
Explanation:
Time can be found by dividing the distance by the velocity. Use the following formula:
[tex]t=\frac{d}{v}[/tex]
The distance traveled was 500 kilometers. The velocity is 150 kilometers per hour.
[tex]d= 500 \ km \\v= 150 \ km/hr[/tex]
[tex]t=\frac{500 \ km} {150 \ km/hr}[/tex]
Divide. Note that the kilometers, or km, will cancel each other out.
[tex]t=\frac{500 \ }{150 \ hr}[/tex]
[tex]t=\frac{10}{3} \ hr[/tex]
[tex]t=3.3333333 \ hr[/tex]
The car traveled for 10/3 or 3.3333 hours
the mass of a car is 1000 kg. how much force would be required to accelerate the car at a rate of 3 m/s^2
Answers
Answer:
The answer is 3000 NExplanation:
The force acting on an object given the mass and acceleration we use the formula
force = mass × accelerationFrom the question
mass = 1000 kg
acceleration = 3 m/s²
So we have
force = 1000 × 3
We have the final answer as
3000 NHope this helps you
find the weight of the following mass;
(a) 220g
please show the formula
Answers
Explanation:
weight=mass*gravity
w=mg
first change 220g to kg like this
1kg=1000g
?=220g
1kg*220g/1000kg=220/1000g
mass =0.22kg
now we can continue
w=0.22kg*10m/s^2 or w=0.22kg*10N/kg
=2.2N =2.2N
hope it helps you

An airport has runways only 145 m long. A small plane must reach a ground speed of 44 m/s before it can become airborne. What average acceleration must the plane’s engines provide if it is to take off safely from its airport?
Answers
Answer:
The value is [tex]a = 6.676 \ m/s^2[/tex]
Explanation:
From the question we are told that
The length of the runways is [tex]l =145 \ m[/tex]
The required ground of a small plane is [tex]v = 44 \ m/s[/tex]
Generally from kinematics equation
[tex]v^2 = u^2 + 2as[/tex]
Here u is the initial speed of the plane which is 0 m/s
so
[tex]44^2 = 0^2 + 2 * a* 145[/tex]
=> [tex]a = 6.676 \ m/s^2[/tex]

8. What are elastic and inelastic collisions?
Answers
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.
An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been transferred to something else.
a jogger runs a distance of 100m and accomplished his feat in 30secs . What was his speed?
Answers
Answer:
His speed was 3.3
Explanation:
To find his speed all you have to do is to divide his distance ÷ time. Since your solving for speed all you do is divide distance ÷ time to find out your speed.
on a standard position vs time graph, the distance between two points on the horizontal axis represents the time interval, and the distance between two points on the vertical axis is the displacement. the slope of the line represents the average velocity

Some researchers are developing a new fertilizer designed to improve the growth of plants in hot, dry climates. The fertilizer was applied to one hundred desert plants in a greenhouse. The average daytime temperature in the greenhouse was 90°F, and the humidity levels were low. Which is best for the researchers to do next?
Answers
Answer:
See the answer below
Explanation:
A compare plants that received fertilizer to similar plants that received none
B begin selling the fertilizer to gardeners living in hot, dry climates
C change the conditions in the greenhouse and retest the fertilizer
D test the fertilizer on plants that are adapted to cooler climates
The best thing to do next for the researcher would be to compare plants that received fertilizer to similar plants that did not receive the fertilizer in order to be able to arrive at an inference of whether the fertilizer is effective or not.
Without comparison, the researchers cannot attribute whatever they observe in the plants to just the effects of the fertilizer. There should be a control group of plants that would be subjected to the same conditions except for the addition of the fertilizer. Whatever differences that are observed in the growth of the two plant groups can then be effectively attributed to the fertilizer.
The correct option is A.

In 1940, the Tacoma Narrows Bridge across the Puget Sound collapsed. The bridge was a suspension bridge. The wind blowing through the narrows matched the natural frequency of the bridge. This resulted in a large movement of roadway, which eventually caused the bridge to fail. What characteristic of waves caused the bridge to collapse? Absorption, because the bridge absorbed all the energy of the wind diffraction, because the wind moved around the bridge, which set the bridge into motion interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridge interference, because destructive interference occurred when the wind frequency matched the natural frequency of the bridge
Answers
Answer:
interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridge
Explanation:
Wave interference occurs when two waves with identical wavelength, velocity, frequency, and amplitude meet each other when the waves travel along with the same medium.
The characteristic of waves that caused the bridge to collapse is interference because constructive interference occurred when the wind frequency matched the natural frequency of the bridge

The BMW has an 85L tank while the Cadillac has a 25 gallon tank. Which one has the larger tank?
Answers
85 Liters would be around 19 to 20 gallons so it's most likely the Cadillac
If The BMW has an 85 L tank while the Cadillac has a 25-gallon tank then the Cadillac would have a larger tank because its 25-gallon tank would be equivalent to 94.635 liters.
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
As given in the problem, the BMW has an 85L tank while the Cadillac has a 25-gallon tank,
1 gallon = 3.7854 liter
25 gallons = 25× 3.7854
= 94.635 liters
If the Cadillac had a 25-gallon tank compared to the BMW's 85-liter tank, the Cadillac would have a larger tank since 25-gallon tanks are equivalent to 94.635 liters.
