ehidna [41]

Answer:5.21 N

Explanation:

Given

B=5.210 T

I=2 A

L=0.5 m

Given Wire is perpendicular to Magnetic field

\theta =90^{\circ}

F=IL\times B

F=BIL sin\theta

F=5.210\cdot 2\cdot 0.5 sin(90)

F=5.210 N

as  1 Tesla =1 N/A/m

Two asteroids in outer space collide and stick together. The mass of each asteroid, and the velocity of each asteroid before the
Alekssandra [29.7K]

Answer:

(5) It depends on whether the collision was elastic or inelastic.

Explanation:

Due to the absence of external forces and the fact that masses and initial velocities are known, it is needed to determine if collision is elastic or inelastic. If collision is inelastic, the Momentum Principle is sufficient to calculate final momentum, but if it is elastic, the Momentum Principle should be complemented with the application of the Energy Principle.

Hence, the correct answer is (5).

When submerged in water, the brick appears to have an additional force pushing it ___upward ___downward. This additional force i
Neko [114]

Answer:

Therefore, the brick appears to have an additional force pushing it upward.

Explanation:

When a brick is submerged in the water, it has two forces acting upon it. One force is the gravitational force or the weight of the brick, that acts downward. The weight force also acts on the brick when it is not in water. But, in water an additional force acts on the brick. This additional force is named as Buoyant Force. This force is equal to the weight of the water displaced by the brick. And this Buoyant Force acts on the brick in the upward direction. The formula for this force is given as follows:

Buoyant Force = (Density of Water)(Volume of Water Displaced)(g)

<u>Therefore, the brick appears to have an additional force pushing it upward.</u>

3–101 It is estimated that 90 percent of an iceberg’s volume is below the surface, while only 10 percent is visible above the su
Artist 52 [7]

Answer:

The density of iceberg upper water and under water are 102.5 kg/m³ and 922.5 kg/m³

Explanation:

Given that,

Volume of seawater = 90 % of Volume of iceberg

Volume of visible surface = 10 %

Density of seawater = 1025 kg/m³

We need to calculate the density of the iceberg

Using equilibrium condition

W_{I}=F_{B}

\rho_{I}\times V_{I}\times g= \rho_{w}\timesV_{w}\times g

Put the value into the formula

\rho_{I}\times V_{I}\times g=\rho_{w}\times0.9V_{I}\times g

\rho_{I}=1025\times0.9

\rho_{I}=922.5kg/m^3

We need to calculate the density of the iceberg

Using equilibrium condition

W_{I}=F_{B}

\rho_{I}\times V_{I}\times g= \rho_{w}\timesV_{w}\times g

Put the value into the formula

\rho_{I}\times V_{I}\times g=\rho_{w}\times0.1V_{I}\times g

\rho_{I}=1025\times0.1

\rho_{I}=102.5\ kg/m^3

Hence, The density of iceberg upper water and under water are 102.5 kg/m³ and 922.5 kg/m³
