Answer:

A distance-time graph shows how far an object has travelled in a given time. It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. Time is plotted on the X-axis

Answer:

[tex]\boxed {\boxed {\sf 252.5 \ Newtons }}[/tex]

Explanation:

Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.

[tex]F=m*a[/tex]

The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:

Substitute the values into the formula.

[tex]F= 50.5 \ kg * 5.0 \ m/s^2[/tex]

Multiply.

[tex]F=252.5 \ kg*m/s^2[/tex]

[tex]F= 252.5 \ N[/tex]

The force required is 252.5 Newtons.

Explanation:

speed : • how fast an object changes position

• miles per hour.

• distance/time.

velocity: • speed in a direction

Explanation:

Answer:Dr. Hess' most significant contribution to the plate tectonic theory began in 1945 when he was the commander of the U.S.S. ... In the paper Hess described how hot magma would rise from under the crust at the Great Global Rift. When the magma cooled, it would expand and push the tectonic plates apart.

Explanation:

Explanation:

Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener's ideas by using the evidence of seafloor spreading to explain what moved continents.

Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through the crust of ocean basins, which would explain why the outlines of many coastlines (like South America and Africa) look like they fit together like a puzzle.

Answer:

Mass on moon = 33.06 kg

Explanation:

Given the following data;

Mass on earth = 200 kg

Weight on earth = 1960 N

Weight on moon = 324 N

To find the mass on moon;

First of all, we would determine the acceleration due to gravity.

Weight = mass * acceleration due to gravity

1960 = 200 * g

g = 1960/200

g = 9.8 m/s²

Next, we find the mass on moon;

Mass on moon = weight on moon/acceleration due to gravity

Mass on moon = 324/9.8

Mass on moon = 33.06 kg

Answer:

Nebulas

Explanation:

Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

Answer:

the velocity of the bullet-wood system after the collision is 2.48 m/s

Explanation:

Given;

mass of the bullet, m₀ = 20 g = 0.02 kg

velocity of the bullet, v₀ = 250 m/s

mass of the wood, m₁ = 2 kg

velocity of the wood, v₁ = 0

Let the velocity of the bullet-wood system after collision = v

Apply the principle of conservation of linear momentum to calculate the final velocity of the system;

Initial momentum = final momentum

m₀v₀ + m₁v₁ = v(m₀ + m₁)

0.02 x 250  + 2 x 0    =    v(2  + 0.02)

5 + 0 = v(2.02)

5 = 2.02v

v = 5/2.02

v = 2.48 m/s

Therefore, the velocity of the bullet-wood system after the collision is 2.48 m/s

Total distance travelled=6 hrs 15 minutes

Total distance=380 miles

[tex] Speed_{avg}=\frac{Total distance} {Total time} \\\\ \to \frac{380 miles}{\frac{25}{4}hrs} \\\\ \to \frac{380 \times 4} {25} \\\\ \to \frac{1520}{25} \\\\ \to 60.8 mph [/tex]

Answer:

7980Pa

Explanation:

1cmHg = 133Pa

60cmHg = 7980Pa

Explanation:

mass=5 kg

potential energy=6000j

height=?

Now

potential energy =m.g.h

or 6000=5*9.8*h

or 6000=49h

or 6000÷49=h

or h= 122.45m

Speed = (distance) / (time)

Speed = (2 m) / (50 s)

Speed = 0.04 m/s

There's not enough information to state the car's velocity. We don't know anything about the direction it moved.

Answer:

119 cm

Explanation:

Given heights :  200cm , 188 cm , 175 cm, 160 cm

since the eyes are at 95% level

95% of 200 cm = 190 cm

95% of 160 cm = 152 cm

hence the allowable height of mirror = 200 - ( 5 + 76 ) = 119 cm

and The mirror should be hung 75cm from the floor

Answer:

h = 122.44 m

Explanation:

Given that,

Mass of a ball, m = 5 kg

Potential energy at the top of the hill, E = 6000 J

We need to find the height of the hill. The formula for the potential energy is given by :

[tex]P=mgh\\\\h=\dfrac{P}{mg}\\\\h=\dfrac{6000}{5\times 9.8}\\\\h=122.44\ m[/tex]

So, the height is 122.44 m.
