Answer:
the lump descends
Explanation:
The full articulation of the query is
Upon fully submerging a 3 kg lump of material in a certain fluid, the fluid that would have occupied the space now filled by the lump weighs 2 kg. (a) When released, does the lump float up, sink, or remain steady
(a)
= Buoyant force acting upward on the lump
= mass of irregular lump = 3 kg
= mass of fluid displaced = 2 kg
The upward buoyant force on the lump is given by the weight of the displaced fluid, thus
the weight of the irregular lump of material is represented as
Given that the weight of the lump downward exceeds the upward buoyant force, the lump will indeed descend
Answer:
The snowball's speed after the impact is 3 m/s
Explanation:
Given the following:
mass of each ball
m₁ = 0.4 Kg
m₂ = 0.6 Kg
initial speed of both balls = v₁ = 15 m/s
Speed of 1 Kg mass post-collision =?
Applying conservation of momentum
m₁ v₁ - m₂ v₁ = (m₁+m₂) V
A negative velocity indicates that the second ball moves in the opposite direction.
0.4 x 15 - 0.6 x 15 = (1) V
Therefore,
V = - 3 m/s
Consequently,
The snowball's speed following the collision is 3 m/s
Answer: A) 2 B) 4 C) 1
Explanation:
The electric field associated with a parallel-plate capacitor is defined as:
A) E=Q/(L^2 * ε0); if we double the charge, the resultant electric field becomes twice as strong as its initial value.
B) Referring to the earlier electric field expression, if the plate size is doubled, the final electric field will be a quarter of the original strength.
C) If the separation distance between the plates is increased twofold, the resulting electric field remains unchanged from its initial state.
Response:
AB = 100 km; BC = 80 km; AC = 180 km
Time of arrival = 11:30
Reasoning:
1. Distance from A to B
(a) Duration of travel
Duration = 10:00 - 8:00 = 2.00 hours
(b) Distance
Distance = speed × time = 50 km/h × 2.00 h = 100 km
2. Distance from B to C
Distance = 80 km/h × 1 h = 80 km
3. Summary of Distances
AB = 100 km
BC = 80 km
AC = 180 km
4. Time of Arrival
Departure from A = 08:00
Travel duration to B = 2:00
Arrival at B = 10:00
Waiting time at B = 0:30
Departure from B = 10:30
Travel duration to C = 1:00
Arrival at C = 11:30
Answer:
Explanation:
