Answer:

Add

Explanation:

When two forces are acting in the same direction then there magnitude are added to each other

Let the first force is $F_1$ and second force is $F_2$ and when they act in same direction then their equivalent will be equal to

$F=F_1+F_2$

When they cat in opposite direction then their equivalent will be $F=F_1-F_2$

Given that average speed is distance traveled divided by time, determine the values of m and n when the time it takes a beam of

SashulF [63]

The distance of earth from sun is 150 million km

We know that one million = 10^6 and 1 km= 10^3 m

Hence 150 million km = 150× 10^6 ×10^3 metre=150×10^9 m

=1.5×10^11 m

The speed of light in vacuum is 2.999... m/s which can be approximately close to 3.0 ×10^8 m/s

We are asked to calculate the time taken by the light beam to reach from sun to earth.

we know that average velocity $v=\frac{distance}{time}$

⇒ $time= \frac{distance}{velocity}$

Here distance=1.5×10^11 m and v=c= 3.0×10^8 m/s

hence time $[t]=\frac{1.5*10^{11} }{3.0*10^{8} } second$

=0.5×10^3 s

=5.0×10^2 s

A correct scientific notation is written as m×10^n [Here m is the magnitude and n is power of 10]

Hence the value of m =5 and value of n =2

What is the difference between mass and weight

Likurg_2 [28]

Mass is a property of an object. It doesn't change, no matter where the object is.

Weight is the gravitational force between two objects. It depends on the masses
of both objects, and also on the distance between their centers, so it changes,
depending on the mass of the OTHER object involved, and on the distance
between them.

A bicyclist is moving toward a sheer wall while holding a tuning fork rated at 488 Hz. 1) If the bicyclist detects a beat freque

gayaneshka [121]

Answer:

speed of the bicycle = 2.81 m/s

Explanation:

given data

tuning fork rated f = 488 Hz

beat frequency fb = 8 Hz

speed of sound vs = 343 m/s

solution

we get here frequency that rider is listening that is

rider hearing frequency = 488 Hz + 8 Hz

rider hearing frequency = 496 Hz

and when it bouncing from sheer wall at frequency of related to stationary object

frequency = 488 Hz + 4 Hz

frequency = 492 Hz

so now we get speed of the bicycle that is

speed of the bicycle = ( $\frac{492}{488}$ × 343 ) - 343 Hz

speed of the bicycle = 2.81 m/s

If Juan upgrades from a sports car to a large truck, what will happen to the

Brrunno [24]

Answer:

The force must increase

Explanation:

According to newton's second law "force is the product of mass and acceleration".

Force = mass x acceleration

Now, the mass of the sports car is lesser compared to that of the truck. Therefore, to take both automobiles to the same speed, enough force must be applied by the engine of the truck.

There must be an increase in the force in order to make both automobiles attain the same speed.
