Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.
Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 mph to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 m/s2 to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
What part of the brain is responsible for the major senses (thinking, hearing, seeing)?
cerebrum |
|
cerebellum |
|
medulla |
|
brainstem |
The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).

In the heart, the __________ artery and vein manage blood flow to the lungs.
pulmonary |
|
capillary |
|
