DedPeter [7]

Answer:

3.71 m/s

Explanation:

From the law of conservation of linear momentum, since we are neglecting minor energy losses due to friction then we can express it as mgh=0.5mv^{2} since all the potential energy is transformed to kinetic energy

Making v the subject of the formula then v=\sqrt {2gh} and here m is the mass of the block, g is acceleration due to gravity, h is the height. Substituting 0.7 m for h and 9.81 for g then we obtain that v=\sqrt {2\times 9.81\times 0.7}=3.705941176 m/s\approx 3.71 m/s

Tabitha knows the redshift value of a particular celestial object. What can she use this information most directly to find out?
AlekseyPX

She can use the information of redshift of a celestial body is to find the age and distance of the object.

<h3>What is red shift?</h3>

'Red shift' is a critical idea for astronomers. The frequency of the light is increased, so the light is observed as moving towards the red side of the range.

Tabitha knows the redshift value of a particular celestial object. She uses this information to observe the consequence of the redshift.

Thus, the red shift value is used to determine the age and distance of the object.

Two objects exert a gravitational force on 8N on one another what would that force be if the mass of both objects were doubled?
jolli1 [7]
Gravitational force of attraction between two objects can be calculated from the following formula:
F = \frac{m_1 \cdot m_2}{r^{2}}
Where m with subscript stands for mass of the object and r is the distance between them.
When we double the mass of those two objects, distance between them stays the same, while in the numerator we have:
2\cdot m_1 \cdot 2 \cdot m_2 = 4\cdot m_1 \cdot m_2
When numerator in the second case 4 times greater than the 'original' numerator and denominator stays the same, force becomes 4 times greater.
