A car moved 60 km East and 90 km West. What is the displacement?

Physics
1 answer:
Reptile [31]3 years ago
7 0

Answer:

We have been given that car is moving 60 km in east

And 90 km in west

That means we are given two different directions  

So, if distance in East is taken to be positive 60 km

Then the distance when car is moving in west direction will be taken as -90 km

So, the displacement means how far the object is from to initial to final position.

So, the displacement will be  (-90)+60 = -30

So, it will be in -30 km (minus is west direction).

umka2103 [35]

Answer:

1.5 × 10^2 J

Explanation:

The initial force, which in this case is the external force is equal to 15N. Logically, when 150 Joules of work is done upon that system the overall energy will increase by that very same amount of work applied on the system which is 150 J.

Homes with multiple bathrooms have outlets connected in series with a red reset button in the system
dybincka [34]

Homes with multiple bathrooms have outlets connected in series with a red reset button in the system. The reason for this circuit design is to prevent electrocution.

<h3>What is red reset button?</h3>

The water heater's reset switch provided on the upper thermostat of an electric water heater. If the button is on, the switch would have tripped and the reset is required.

To prevent any kind of injury or killing of a person by electric shock is called as the electrocution. This can be prevented only by outlets connected in series with a red reset button.

Thus, the reason for this circuit design is to prevent electrocution.

A force of 880 newtons stretches a spring 4 meters. A mass of 55 kilograms is attached to the end of the spring and is initially
zysi [14]

Answer:

x(t) = -8sin2t

Explanation:

See the attachment for solution

From my solving, we can deduce that w² = 4, and thus, w = 2

Therefore, the general solution is

x(t) = c1 cos2t + c2 sin2t

Considering the final variable, we can conclude that

x(0) = 0

x'(0) = -8 m/s

The final solution, thus

x(t) = -8sin2t

scZoUnD [109]
<span>Generally speaking, the level of molecular motion is highest in gases, where molecules move around freely in space, bouncing off of each other, and lowest in solids, where molecules are bound together in a rigid structure. As such, the answer would be A; "the molecules in air move more than the molecules in wood".</span>
