If a planet has more mass, the acceleration of gravity you feel on that planet will be greater than on a planet with less mass. true or false

Answer:

force meter

Explanation:

Answer:

Wrong, the correct answer is "newton"

Explanation:

1 Newton = 1 kilogram-meter per second2

Multiply the masses by the respective distances:

(12 kg) (2 m) = 24 J

(25 kg) (1 m) = 25 J

so the heavier bag takes more work to lift, and (b) is the answer.

(d) is technically correct if the sacks are carrying different contents whose masses are not equal, but since we don't know what's inside each sack, assume 12 kg and 25 kg are the masses of each sack *and* their contents.

True- just pick true

Durante los primeros 120 km, se nos dice que la velocidad es de 60 km / h.

sabemos que velocidad = distancia / tiempo

por lo tanto, distancia = velocidad * tiempo

deja que el tiempo sea ty la velocidad sea s

distancia = s * t

distancia = 60t -------------------- 1

Segundo paso:

Durante los segundos 80 km, se nos dice que la velocidad es de 90 km / h.

sabemos que velocidad = distancia / tiempo

por lo tanto, distancia = velocidad * tiempo

deja que el tiempo sea ty la velocidad sea s

distancia = s * t

desatancia = 90t ------------------- 2

La distancia total recorrida es de 200 km.

entonces 200 = 60t + 90t

200 = 150t

t = 200/150

t = 1,3 horas

Por lo tanto, el viaje tendrá una duración de 1 hora y 20 minutos aproximadamente.

Answer:

Abdul has an apparent weight of 600 newtons.

Explanation:

The statement is incorrectly written. Its correct form is:

Abdul of mass 50 kg is standing in an elevator of his building. The elevator is moving upwards and is slowing down at a rate of 2.0 m/s2. What is Abdul's apparent weight? Use g = 10 m/s2.

According to the statement, we know that elevator and Abdul himself are moving upwards and decelerating, which means that Abdul feels a force from elevator is the same direction of his weight. From 2nd Newton's Law we find the following equation of equilibrium:

[tex]\Sigma F = F-m\cdot g = m\cdot a[/tex] (1)

Where:

[tex]F[/tex] - Apparent weight, measured in newtons.

[tex]m[/tex] - Mass of Abdul, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]a[/tex] - Net acceleration of the elevator-Abdul system, measured in meters per square second.

In (1) we clear the apparent weight:

[tex]F = m \cdot (a+g)[/tex]

If we know that [tex]m = 50\,kg[/tex], [tex]a = 2\,\frac{m}{s^{2}}[/tex] and [tex]g = 10\,\frac{m}{s^{2}}[/tex], we find that the apparent weight of Abdul is:

[tex]F = (50\,kg)\cdot \left(2\,\frac{m}{s^{2}}+10\,\frac{m}{s^{2}} \right)[/tex]

[tex]F = 600\,N[/tex]

Abdul has an apparent weight of 600 newtons.

Answer:

1) For the swung puck tied to the string that has a mass m₁ and having another mass m₂ attached to the string that passes through a hole in the table, such that m₂ > m₁

The swung puck rotating on the table is kept in the circular motion on the table by the centripetal force acting towards the center of its rotation along the string, which is given by the amount the weight of m₂ exceeds m₁, in the same way a planet moving around the Sun is kept in its orbit by the gravitational attraction between the planet and the Sun.

2) i) The forces acting on the puck are;

a) The centripetal force in the string, acting inward, towards the center of rotation provided by the weight of m₂

b) The centrifugal force of the puck, acting outward, tending to continue its motion in a straight line

ii) The forces acting on the planet are;

a) The force of gravitational attraction between the planet and the Sun, acting towards the Sun, such that, the planet revolves around the Sun

b) The centrifugal force of the planet, acting outward, tending to move in a linear or straight path

Explanation:

Forces on Puck  Swung

Centrifugal Force (Outwards from  puck swung  )

Tension( Towards the center)

Forces on the Planet

Centrifugal Force (Outwards from  Planets  )

Gravitational Force ( Inwards towards Sun )

Let us suppose that the

The  puck swung is connected with a center at a distance of radius  r

so it is revolving around the point  just like planets revolve around the Sun.

The Centrifugal  Force and Gravitational Force  causes the planetary motion around the sun.

The Centrifugal force is an outward force  and is observed  from the accelerated frame of reference , In our case Planet and  puck swung are    the accelerated frame of references.

The Gravitational Force between the Sun and the planets  (directed towards Sun) is balanced by Centrifugal Force.

Let us consider that the string of  puck swung has negligible mass

So the Tension which is directed towards the center will provide the  force to counterbalance the centrifugal  force acting on puck swung.

So Tension will act towards the center in case of puck swung and centrifugal force will act outwards.

Answer:

The circumference of planet tirth is [tex]C = 90000 \ km[/tex]

Explanation:

From the question we are told that

   The distance of tyene from the observer is  [tex]d = 750 \ km[/tex]

   The altitude of the sun from the equinox is   [tex]\theta_s = 87.0^o[/tex]

Generally given that on the equinox your sun is directly overhead in the city of tyene , then the altitude of the tyene from the equinox is  [tex]\theta_e = 90 ^o[/tex]

Generally the angular distance between tyene and the sun as observed from the equinox is mathematically represented as

         [tex]\theta _d = \theta_e - \theta_s[/tex]

=>       [tex]\theta _d = 90 -87[/tex]

=>       [tex]\theta _d =3^o[/tex]

Generally the ratio of [tex]\theta _d =3^o[/tex] to  [tex]360^o[/tex] which is the total angle in a circle is equal to the ratio of  [tex]d = 750 \ km[/tex] to the circumference of the planet

So

         [tex]\frac{\theta_d}{360} = \frac{750}{C}[/tex]

=>      [tex]\frac{3}{360} = \frac{750}{C}[/tex]

=>     [tex]C = 90000 \ km[/tex]

Answer:

The mammoth bone is 22726 years old.

Explanation:

We can find how hold is the mammoth bone using the decay equation:

[tex]N(t) = N_{0}*e^{-\lambda t}[/tex]   (1)

Where:

N(t): is the quantity at time t = 6.25%N₀

N₀: is the initial quantity

λ: is the decay constant

First, we need to find λ:

[tex] \lambda = \frac{ln(2)}{t_{1/2}} = \frac{ln(2)}{5700 y} = 1.22 \cdot 10^{-4} y [/tex]

Now, by solving equation (1) for t we have:

[tex]t = \frac{ln(\frac{N(t)}{N_{0}})}{-\lambda} = \frac{ln(0.0625)}{-1.22 \cdot 10^{-4}} = 22726 y[/tex]      

Therefore, the mammoth bone is 22726 years old.

Answer:

82.7 m

Explanation:

u= 22m/s

a= 2.4 m/s^2.

t= 3.2 secs

Therefore the distance travelled can be calculated as follows

S= ut + 1/2at^2

= 22 × 3.2 + 1/2 × 2.4 × 3.2^2

= 70.4 + 1/2×24.58

= 70.4 + 12.29

= 82.7 m

Hence the distance travelled by the truck is 82.7 m

An iron bar whose initial length is 2m has its temperature increased from 20 ° C to 120 ° C. What is the final length of the bar? (consider that the coefficient of expansion of iron) is 1.2 x 10-5 1 / ° C (3 points)

Given that,

Initial length of an iron bar, [tex]L_0=2\ m[/tex]

The temperature increased from 20°C to 120°C

The coefficient of expansion of iron is [tex]1.2\times 10^{-5}\ /^{\circ} C[/tex]

We need to find the final length of the bar.

The linear expansion equation is given by :

[tex]\Delta L=\alpha L\Delta T[/tex]

Where [tex]\Delta L[/tex] is the change in length

[tex]\Delta L=1.2\times 10^{-5}\times 2\times (120-20)\\\\=0.0024\ m[/tex]

Also, [tex]\Delta L = L_o-L[/tex]

L is final length

[tex]0.0024= 2-L\\\\L=2-0.0024\\\\=1.9976\ m[/tex]

So, the final length of the bar is 1.9976 m

Answer:

A) 5m/s

Explanation:

Momentum of ball in one direction=momentum of cannon in other direction

mv = mv

(10)(500)=(1000)v

5000=1000v

∴v=5m/s

When a ball is fired with a velocity its momentum remains conserved. The recoil velocity of the cannon is 5m/s.

The velocity with which the cannon is pushed backwards after firing is called the recoil velocity.

The momentum remains conserved . So, according to the momentum conservation principle, initial momentum is equal to the final momentum.

Mu +mu=Mv +mv

where, M is the mass of cannon and m is the mass of ball.

u is the initial velocity and v is the final velocity.

10 kg ball is fired with a velocity of 500 meters per second from a 1,000 kg cannon.

mu = Mv

(10)(500)=(1000)v

5000=1000v

v=5m/s

Thus, the recoil velocity of the cannon is 5 m/s.
