Answer:
Momentum of elephant is greater than momentum of tranquilizer dart
Explanation:
= Mass of elephant = 2140 kg
= Mass of tranquilizer dart = 0.0415 kg
= Velocity of elephant = 7.63 m/s
= Velocity of tranquilizer dart = 619 m/s
Momentum of elephant
Momentum of tranquilizer dart
So, 
Momentum of elephant is greater than momentum of tranquilizer dart
A negative mutation can make asexually produced organisms susceptible to disease and can destroy large numbers of offspring. Some methods of asexual reproduction produce offspring that are close together and compete for food and space. Unfavourable conditions such as extreme temperatures can wipe out entire colonies.
Answer:
Explanation:
Read forces directly from the graph.
Read displacements directly from the graph.
Use the area under the graph to find the work done by the force. This is equal to the kinetic or potential energy the object gains due to the application of the force.
Answer:
Check below for the explanation
Explanation:
Since it is stated that the ring is dropped from a height, h, through a non uniform magnetic field, two kinds of force will act on the ring, namely:
- A magnetic force (that is non uniform since the field is non uniform)
- Gravitational force
A certain amount of torque is provided by the non uniform magnetic force on the ring while the force gravity pulls it down. Due to the downward pull by the force of gravity on the ring and the torque acting on it as a result of the non uniform magnetic force, the ring begins to rotate.
Answer:
Energy converted = 
Explanation:
Recall that Power is the rate at which energy is transferred therefore defined by the mathematical formula: 
Since the information on the power of the runner is given, as well as the time the energy conversion takes place, we can then use this equation to find how much energy is been converted. Notice that we just need to change the given time *10 minutes) into the appropriate units (seconds)to get the answer in SI units of energy (Joules). The conversion of 10 minutes into seconds is done by multiplying : 10 minutes * 60 seconds/minute = 600 seconds.
We use this then to find the energy converted by the runner:
